山东交通学院教务处二零二一年六月摘要在女性主义看来,女性是人类个体璀璨的历史,具有独立的、理想的光辉,她们在人类社会发展进程中发挥着不可取代的历史性作用,同时,她们也是一支易被世人低估的力量。

女性主义的出现极大程度上瓦解了男权社会与父权制的社会结构,使女性提高主体意识,实现个体解放成为可能。

《暮光之城》是哥特小说中彰显女性主义的典范之作,无论是在场景构图、人物塑造还是在主题渲染方面,都以女性视角为体验轴心,侧重画面的唯美感、情节的凄美感和人物的柔美感,主旨层面则突出女性主体意识的觉醒。

《聊斋志异》作为蒲松龄的“孤愤之书”,塑造了一系列形象各异的女性人物,其中部分女性角色身上都洋溢着与那个封建时代格格不入的女性主义意识。

因此,本文以《暮光之城》和《聊斋志异》为研究对象,探析这两部小说中的女性主义。

关键词:《暮光之城》,《聊斋志异》,女性主义From the perspective of feminism,women are the brilliant history of human individuals, with independent and ideal brilliance.They play an irreplaceable historical role in the development of human society.At the same time,they are also a force that is easily underestimated by the world.The emergence of feminism has disintegrated the social structure of patriarchal society and patriarchy to a great extent,making it possible for women to increase their subject consciousness and realize individual liberation.The Twilight Saga is a model of feminism in Gothic novels.Whether in scene composition,character creation or theme rendering,it takes the female perspective as the experience axis,focusing on the aesthetics and plot of the picture.The poignant beauty and the feminine beauty of the characters,and the theme level highlights the awakening of female subject consciousness.As Pu Songling's“Book of Solitary Anger”,Strange Stories from a Chinese Studio has created a series of female characters with different images.Some of the female characters are permeated with feminist consciousness that is incompatible with that feudal era.Among the classics,the feminist color is even stronger.Therefore,this article takes Strange Stories from a Chinese Studio and The Twilight Saga as the research objects to analyze the feminism in these two novels.Key

Western society in the second half of the 19th century.The emergence of feminist thoughts is not only an important theoretical advancement in the development of human history,but also an epoch-making historical progress.Throughout history,female groups have played the role of being enslaved,oppressed,and ruled in both Eastern and Western societies.The emergence of feminist thought not only gave women the impetus for individual liberation,but also provided a way for human development to face up to mankind itself from a diverse perspective,and face the historical development of mankind with the courage of the courage of both sexes to develop together and equality.A new mode of thinking and a way out for development.In the historical evolution of Western society,women undoubtedly played an inestimable role in advancing,especially feminist theories.In fact,women's contribution to society in a patriarchal society is far more than people understand.Female culture liberates women from a patriarchal society and enables them to gain more freedom,equality and respect..To a certain extent,feminism,as the theoretical position of the female group,has an extremely important supporting role for female individuals.At the same time,feminist culture has more indirectly promoted the diversified transformation of society,enabling human beings to acquire a new mode of thinking in their own evolution and evolution.The Twilight Saga is a model of feminism in Gothic novels.Whether in scene composition,character creation or theme rendering,it takes the female perspective as the experience axis,focusing on the aesthetics and plot of the picture.The poignant beauty and the feminine beauty of the characters,and the theme level highlights the awakening of female subject consciousness.Strange Stories from a Chinese Studio,as Pu Songling's“Book of Solitary Anger”,portrays a series of female characters with different images.Some of the female characters are permeated with feminist consciousness that is incompatible with that feudal era.The feminist in the novel The color is even stronger.The chivalrous girl embodies a strong sense of independence, self-determination and control of her own destiny,as well as contempt and flogging of feudal etiquette.Therefore,starting from these two novels,the main purpose of this article is to discover the greatness of women in the patriarchal society by exploring feminism.In comparison,male culture has always appeared in front of people in a social mainstream posture.Therefore,studying female culture is not only an inherent requirement of female culture itself,but also the primary task for the overall progressof human culture as a whole.At the same time,although the existing male culture in the society has matured and has a certain degree of systematization,there are still many unreasonable,unhealthy and unfavorable problems for the overall development of men.The new development requirement of female culture is a modification of male culture from the side.Therefore,the analysis of female culture is an important attempt to promote the entire human culture as well as male culture,and it has important theoretical and practical significance for progress.In summary,this article takes The Twilight Saga and Strange Stories from a Chinese Studio as the research objects,and discusses in detail the feminism in the two novels from the three aspects of setting,character and theme.1.BackgroundFrom the women in The Twilight Saga and Strange Stories from a Chinese Studio, we can see that under the influence of traditional thinking and authoritarian thinking that a woman is virtue at the time,many women do not possess independence. Thinking,most of them possess the qualities of pursuing freedom,daring to resist,and being brave.1.1The Twilight SagaThe Twilight Saga is a series of novels written by American writer Stephanie Meyer,including Twilight,New Moon,Lunar Eclipse and Breaking Dawn.This series of novels describes the love story of the young girl Isabella Marie Swan and the handsome and elegant vampire award Cullen.1.1.1About Stephenie MeyerStephenie Meyer was born in Arizona,USA.She has been reading a lot of books since she was a child,and she has chosen to read those heavy and big books,because she likes long stories,so she doesn't want to let them end early.Sometimes after reading a book,she continued to make up the story on her own.Although Stephanie likes to read very much and majored in English literature in university,she did not participate in any creative writing courses in the four years of university.She didn't create a work that satisfies her.Instead,she was very satisfied with the marriage: Stephanie met her childhood playmate Chris Qiang when she came home from vacation.The two got married before she graduated.She believes in childhood sweethearts and love at first sight,as well as the gods of marriage and sex.Her attitude towards love is also reflected in her novels.When the publisher asked her to add the sexual description of Bella and Yan Dehua in the novel before their marriage, she immediately rejected her,and Stephanie positioned herself after marriage.For a good wife and a good mother,the New Year passed smoothly.Until she was30years old,she was the mother of three children,and she was no longer satisfied with being a good housewife when Qingchun flew away.She felt that she had to do something more to realize her personal value.At midnight on January23,2003,she had an unforgettable dream:on the beautiful soft forest and grass,an ordinary high school girl lay there with a beautiful and surprising vampire beside them.It was so vivid and real,and Stephanie was fascinated by it.After she woke up,she played on the horse and tried to record thedream.At that time,the child was still crying,and Stephanie sat in front of the computer holding him,typing hard with one hand.For the next few days,Stephanie has been obsessed with this dream.She sits in front of the computer and type when she is free,and when she is not free,she thinks about stories in her mind.Just like when she made up a story to herself when she was a child,she wanted to know what would happen later.But all of this is done in secret.She didn't have the courage to tell her devout husband that she was writing a vampire story!Unlike the cruel and terrifying vampires in the past,the vampires described by Stephanie are kind-hearted,biochemical,and romantic.Stephanie uses her profound knowledge of English language and literature and rich imagination to present the life and death of Romeo and Juliet,the elegance and ridicule of Pride and Prejudice,and the entanglement of Wuthering Heights.And conflict,all of this is presented in an extremely easy way,and the lingering color of tragedy hidden under the veil of love is as simple and desolate as the ancient Greek drama,all these made the legend of The Twilight Saga.1.1.2Introduction of The Twilight SagaThe Twilight Saga series of novels is the representative work of American female writer Stephanie Meyer,including Twilight,New Moon,Lunar Eclipse,Breaking Dawn and other chapters,it tells the romantic love story between the weak and melancholy girl Bella and the handsome and charming vampire Edward.The novel changes the horror and bloody of the Gothic novels of the past,and instead takes the female perspective as the axis of experience.The scenes are hazy and beautiful.The character description focuses on women's mentality and life perception,and the theme rendering emphasizes the self after women's growth and transformation.Awakening and motherhood are highlighted,and the whole work is permeated with a strong feminist color.The most obvious difference between The Twilight Saga series of novels and traditional Gothic novels is the arrangement of the scenes.Traditional Gothic novels often use dilapidated and gloomy castles or bleak wilderness as the setting, highlighting a sense of strangeness and horror on the screen,showing the virility and violence of men.The Twilight Saga weakens this gloomy feature based on female aesthetics, revealing a soft and beautiful atmosphere:the vast forest is flooded with sunshine, becoming a place of love for the hero and heroine;the dilapidated castle is replaced by tranquility Gorgeous villas make people linger;vampires and werewolves ofterrifying colors are transformed into beautiful and righteous teenagers;youthful and beautiful,ups and downs of love stories create a warm and romantic atmosphere.The location of the whole story is set in a small town that is rainy all year round.Although the color is biased towards the cool gray and blue,most of the plot scenes are arranged in the verdant jungle and on the lush grass,accompanied by golden Sunshine, delicate flowers,dexterous animals,etc.,are all reappearances of natural beauty,and its purity and softness need not be said too much.In addition,in order to ensure the continuity of this aesthetic scene,the fighting and killing scenes in the novel are also treated as understatement and implicit,which greatly takes care of women's psychological expectations and acceptability,and conforms to women's aesthetic taste.1.2Strange Stories from a Chinese StudioStrange Stories from a Chinese Studio as Pu Songling's“Book of Solitary Anger”, created a series of female images of different shapes,and they are permeated with feminist consciousness that is incompatible with that feudal era.1.2.1About Pu SonglingPu Songling was very enthusiastic about the imperial examination fame.This is due to family traditions,social system and atmosphere at the time,and his own specific circumstances.His family and ancestors have been small landlords throughout the world.They all read books,but their fame is not developed.It seems that they are only talented scholars,and there are no such people.The feudal society in China is centered on familyism.A person's social status is mainly determined by the reputation and status of his family.The writing of"Strange Tales from a Lonely Studio"also clearly shows this point,and his grievances and dissatisfaction,and his thoughts and feelings are also permeated in the work.But we know that the living conditions of the chilly bird hugging the tree and the autumn insect hanging on the moon are a description of his personal life and experience,and at the same time,it is also an overview of the actual situation of the people of Guangda in the early Qing Dynasty.The story of Qinglin Hesse,which he deliberately collected and wrote with great enthusiasm and perseverance,is also the story that the people in the dark society at that time relied on the fantasy creation,and they loved to hear and see.Here,his personal grievance and resentment have become the bridge between him and the people.If there is no personal dissatisfaction,he will ride on the people,oppose thepeople,and will not tie his heart to the people),his personal poor situation,It is the same real soil as the life reality of the people.Therefore,in his works,on the main issues,he can stand on the side of the people at the time,encourage people to work hard to look at the good with what he knows and persist in,and teach people what he knows to distinguish between right and wrong,such as Send charcoal in severe winter, like light in darkness.Both the charcoal and the lamp came from the people,and they warmed oneself,but on the other hand,they came and went to illuminate the people and warm the people.This point cannot be ignored.1.2.2Introduction of Strange Stories from a Chinese StudioStrange Stories from a Chinese Studio,as Pu Songling's“Book of Solitary Indignation”,has created a series of female images of different forms,and they are permeated with feminist consciousness that is incompatible with that feudal era.Pu Songling’s Liao Zhai women are beautiful,beautiful,beautiful,beautiful,and in them, people can see that under the traditional ideology and authoritarian ideology that “women without talent is virtue”are generally believed at that time,Many women do not possess independent ideas.Most of them possess the qualities of pursuing freedom,daring to resist,and being brave.There are many women in“Strange Tales from a Lonely Studio”,and people can explore their feminist charm.The economically independent women described by Pu Songling vividly appear in front of readers with an image of independence and courage.They not only maintain individual independence,but also maintain economic independence.From their bodies,people see not only the images of women,but also the feminist consciousness behind them.Therefore,studying the stories,behavior and wisdom of Liao Zhai women is of great significance to women today.1.3The development of feminismIn the1980s,internal conflicts in feminist theories became increasingly intensified.One point of view tends to ignore the grand theory and pay attention to the specific issues at the micro level.Another view is that the essentialism of gender identity prevails,and essentialism is still promoted in practice.But"equality"is not “same”,gender equality between men and women should take into account the differences in the characteristics of both parties,and fully respect the identity of their important qualities,so as to truly realize the true liberation of women as"human-like" individuals.Therefore,when feminist theories still have no more in-depth research on the difference phenomenon,we should explore this difference phenomenon moredeeply.Feminism should treat sex and gender differently,and use a historical attitude to recognize the existence of sexual differences.This is also the value of the existence of men and women and should not obliterate their respective characteristics.Instead, focus on the root causes of gender differences that cause the unequal status of men and women.Cultural,historical,and linguistic,these are the sources of gender differences.If you want to make women and men equal,ultimately achieve gender differences.For common development and equal development,we must seek a cultural path to change gender differences.In this way,only post-modern feminism is a new exploration to make feminism out of its predicament.2The image-shapingThe feminism in The Twilight Saga and Strange Stories from a Chinese Studiois embodied in various details in the novel,and the most important thing is the most obvious in image shaping.Therefore,this part discusses the feminism of these two novels in detail.2.1In The Twilight SagaThe feminism shown in The Twilight Saga is mainly shaped and completed by the character of Bella.With the personal experience and growth of the heroine Bella as the background,the feminism of Bella and Edward's family is introduced.2.1.1The analysis of the plotThe Twilight Saga is different from other novels of the same type,such as Interview with the Vampire and Four Hundred Years of Fright,which is filled with a terrifying atmosphere.On the contrary,the environment in the plot design of "Twilight"is beautiful and not dark.The overall color of the novel is gray-blue,which is slightly deep and not frightening.This colder color invisibly casts a mysterious and sensual color on the film.On the basis of gray and blue,lush green forests and fresh campuses add a bit of vitality and vitality to the novel.This kind of plot rendering can be seen everywhere in the novel.This novel also attracted many female audiences because of its cold and mysterious plot.The Twilight Saga does not use a lot of cold and strange plots to attract the audience,but uses delicate details to create a soft atmosphere invisibly.An important place in the novel is the forest where Bella unlocked Edward's identity.In the forest, the old trees are verdant,the branches circling and bending,and the faint mist adds a deep sense to the plot of the whole novel.For female audiences,it is a sense of mystery and happiness to truly understand each other in a mysterious and secluded space and witness the unraveling of their true identity.The novel's treatment of this kind of plot satisfies women's pursuit of a certain sense of ritual to some extent.2.1.2From BellaBella’s female subject consciousness is first reflected in her independent choice of fate and life.Whether it is an emotional choice with Edward or whether to become a vampire,Bella has embodied her own ideas as an independent social individual. Through this,Stephanie Meyer has created an image of a woman who can makeindependent decisions about her own destiny and life.At the same time,the literary work The Twilight Saga has a distinct feminist consciousness and feminist color.In the course of Bella's independent choice of fate,the resistance brought about by the interference of the patriarchal society is far greater than the pain that the body needs to bear.As a local sheriff,Bella’s father could not accept his daughter’s transformation into a vampire that everyone hated,and he always held a negative attitude towards her choice;although Edward loves Bella deeply,he can't bear to lose his humanity and soul and give up his good years.As a werewolf,Jacob is not in harmony with the vampire family,and he can't accept that his beloved Bella becomes a vampire.idea.Therefore,although Bella made a resolute decision about her destiny,she was still unable to succeed.It can be seen that the intervention and manipulation of masculinity are thorns that women must cut off on the road to self-realization.Bella got pregnant unexpectedly after marriage.Despite the opposition of everyone,she tried her best to save the fetus.At the time of childbirth,her life was dying.Edward had to inject venom into her body at the last minute,helping Bella finally realize the transformation from human to vampire.,Realized her choice of self-destiny.Through her perseverance and hard work,Bella broke through numerous obstacles,made men compromised,realized the equality of individual lives between men and women,and reached the state of women's ideal self.2.1.3From Edward and his familyIf Bella’s image is not meant to cater to male audiences,then Edward’s image caters to the female visual experience to a large extent.Edward has a fair complexion, a cold face,a slender figure,yet strong,and his clothes are simple but not simple. Even when the sun was shining and he thought he was terrible,his body just shone like a crystal diamond,and there was no frightening change.From the perspective of the appearance of the characters alone,the film The Twilight Saga has broken through many places that the film has not yet broken through.But now that men have the right to speak,women seem to have gradually accepted the male aesthetic standards to judge themselves,and are accustomed to accepting others to evaluate themselves.If one day,when male roles that cater to women can be accepted by the world just like female roles that cater to men,then the world that feminism pursues will be a big step closer.Bella came to Edward's house for the first time,and Edward's family was busy for her arrival.Considering that Bella is a human being,Edward's family uses thekitchen to make Italian dishes for her.And Edward's parents also expressed joy at Bella's arrival.This kind of respect,regardless of whether Bella is a human who may cause great trouble to the Edward family,is not everywhere even in the real world. While avoiding the hunting of James the hunter,the Edward family was fully deployed.Facing the huge trouble of Bella at this time,the Edwards never seemed to want to abandon her.In their hearts,Bella was already a family member.Even Rosalie, who was dissatisfied midway,put on clothes that smelled of Bella under the persuasion of her father Esme,and exposed herself to danger to protect Bella.2.2In Strange Stories from a Chinese StudioPu Songling has created many images with feminist consciousness.It can be seen from Strange Stories from a Chinese Studio that these women have independent personalities,dare to break through themselves,and can participate in social and economic activities under the social background at that time,and work hard to get rich.Mastering economic power,grasping one's own destiny,and deciding one's own life,this kind of characteristic that modern women can have is amazing.2.2.1Women with independent financial abilityIn Strange Stories from a Chinese Studio,compared with the female businessmen recorded in the past,Pu Songling has portrayed a series of shrewd and modern female businessmen who,like men,have the courage to shoulder the burden of family livelihood.Some are even more brilliant and have achieved greater achievements than men.In previous historical materials or literary works,there are often mentions and descriptions of female businessmen,but they have a professional understanding of women businessmen and their careers.The concept is rarely clearly stated,and as far as a single bibliography is concerned,the number of female businessmen and the depth of their actual participation in business activities seldom reach the complete presentation of Strange Stories from a Chinese Studio.The economic independence of women in the early Qing Dynasty embodied in Strange Stories from a Chinese Studio can be said to be that these women have a strong sense of operation and management,from category selection,venture capital financing,financial management,production management,technological improvement and innovation,Business distribution,business philosophy,social responsibility,etc.,can be said to be commercial details that other works don't have, and they can appear in the text alone to show the natural nature of women in business. The female businessmen of Strange Stories from a Chinese Studio,they are smart andcapable,good at business,and can manage well,which makes the male businessmen in the article less attractive.They can support their families and even become big businessmen.His body embodies the author Pu Songling’s new era merchant thoughts and female merchant consciousness.These women include Shanshan,Xi Liu,Xiao Er and so on.Through the excavation of female businessmen in Strange Stories from a Chinese Studio,we found that women are engaged in different business affairs.The author believes that women who leave the family have two advantages.First,they shift from“distribution of profits”to“generating profits”,and they can engage in a certain profession to achieve a self-supporting life level.They are beneficial to the country and the people.Second,the behaviors they practiced can also give their children the power of example,and can“guide according to the situation”,and they often play an exemplary role in the whole family."2.2.2Female images with revenge consciousnessThe targets of revenge for women in Strange Stories from a Chinese Studio are mainly corrupt officials,landlords and tyrants,villains and rogues who abuse the common people.There are sympathetic and lamentable experiences and encounters in every woman who is vengeful.Although the revenge motives and causes of revenge women in Strange Stories from a Chinese Studio are different,they can generally be divided into the following two categories:The first is revenge for relatives,which refers to a vengeful act of revenge women take when their parents,brothers,sisters,husband,in-laws and other relatives are framed and killed by the wicked.However,there are many chapters in Strange Stories from a Chinese Studio that describe the stories of women avenging their relatives.Some of them,as daughters-in-law,avenge the victimized in-laws.For example,the young woman Gengniang in Geng Niang revenges the in-laws who were pushed into the water by the vast ocean:some are as fiances to avenge the victimized fiance,such as the prostitutes in Xiao Waiting.Xihou takes revenge for his fiancéframed by a wealthy businessman.Among the women who avenge their relatives, most of them are daughters to avenge the victim's father.For example,the girl Shang Sanguan in Shang Sanguan is to avenge the father who was beaten and killed by Yi Hao for no reason:The chivalrous girl in The Swordsman is revenge for the father who was framed to death by the enemy.In the plot description of revenge for relatives, in addition to vividly showing the spirit of resistance and struggle in these avenging women,it also shows their filial piety as daughters,wives and daughter-in-laws.Second,revenge for others.It mainly refers to the revenge behavior of revenge women for those who are not related to them.This kind of revenge behavior can best reflect the chivalrous spirit of revenge women to protect the strong and support the weak and eliminate violence and peace.There are no lack of such chivalrous revenge women in Strange Stories from a Chinese Studio,such as the Yunnan mountain woman in Lord,who took the initiative to avenge the murdered passer-by to the vicious giant:The lone maid in Xin Fourteen Mother was unprovoked by Feng Sheng. When Mr.Yintai was trapped in Tutu and had nowhere to avenge justice,he stepped forward to avenge the victim Feng Sheng.Among the women who avenge others,the most commendable is the peasant woman Zhang in Zhang's Women.She took the initiative to avenge the victims of women when the fierce and licentious extermination of soldiers wantonly raped women.She used clever tricks to attack frequently,and with her weak body,she killed three shameless and obscene soldiers one after another.In the above two descriptions of revenge,if the first kind of revenge is somewhat passive,then the second kind of revenge is undoubtedly more active.Especially when the person who takes the initiative to avenge others is a woman,it is even more commendable.However,whether it is revenge for relatives or others,the revenge of these avenging women is to resist evil and uphold justice,which is worthy of strong recognition and praise.2.2.3The elimination of traditional novel modelIn the long feudal society,men are at the center of society,women have always been at the bottom of the society,in a subordinate position in the family and society, and endured all kinds of unfair treatment.Women follow the set formed by the accumulation of feudal society for thousands of years.“Three outlines and five perseverances”,“Three obeys and four virtues”have become standard women of filial piety,daughter-in-law,virtuous wife,good mother,and kind aunt.These regulations are nothing more than depriving women of their freedom and human rights and treating women as child-bearers.Women's tools and slavery to be submissive.In many works of Strange Stories from a Chinese Studio,women showed strong contempt for feudal ethics in the process of pursuing love.For example,the female ghost Xiao Xie and Qiu Rong teased Tao Sheng in the feudal society.This kind of careless play of a woman with a strange man can be said to be unconventional,but we will be touched by Xiao Xie's innocent romance,boldness,implicit shyness,calmness and passion.Feng's father severely reprimanded Hongyu for such an unworldly。

交通工程专业毕业论文(5篇模版)

交通工程专业毕业论文(5篇模版)

交通工程专业毕业论文(5篇模版)第一篇:交通工程专业毕业论文古典文学常见论文一词,谓交谈辞章或交流思想。

当代,论文常用来指进行各个学术领域的研究和描述学术研究成果的文章,简称之为论文。

以下是小编整理的交通工程专业毕业论文,欢迎阅读!1交通工程专业毕业设计选题分析我校交通工程专业毕业设计可分为毕业设计及毕业论文两类。

选题的来源一般为教师自拟题目或科研项目中的某一部分,选题总体来说比较丰富,包括交通工程各领域,如交通设计、道路设计、道路桥梁结构分析等。

总体上而言,我校交通工程专业选题范围较广,基本上涉及到了交通工程的各个方面,且与学生的就业方向具有较好的相关性。

但由于指导教师专业方向的限制,学生能力的限制以及教学条件的限制,学生选题的自由度实际上不大。

在设计类题目中,“交通设施设计”中采用的题目大多就有很强的工程背景或实际背景,如“建设一路公路改造设计”。

此类题目由于具有很强的工程背景,可以为学生提供比较全面的资料,如实际的地形图、地勘报告等,学生参与的兴趣较高,而题目又涉及到实际工程中各方面问题,若师生之间能进行良好的互动,可取得更好的教学效果。

“交通设计”则主要针对道路交叉口或者一定区域内的道路网进行交通分析,在此基础上进行交通优化设计,如“武汉市二环东段道路出入口控制设计”。

此类题目一般以实际问题为依托,学生需要自己采集交通数据及道路数据,在此基础上进行交通模拟分析并对原设计方案进行优化。

“交通信息”则主要涉及到信息工程在交通领域的应用,如“基于Sketch-up的校园三维场景模型的构建”,此类选题需要学生有一定的专业软件能力,具有较强的应用性。

论文类题目中也可分为3个方面,分别为“结构与材料性能”、“交通策略”和“交通信息”。

一般而言,毕业论文涉及到的专业知识相对而言较少,一般仅对某一门课程中一方面的问题开展研究。

其一方面需要学生有扎实的专业基础,另一方面要求学生有一定的科研能力,因此论文在全部设计中占有的比例不宜过大,本专业要求一般不高于20%。

美国混凝土协会对大体积混凝土的规定为:“任何就地浇筑的大体积混凝土,其尺寸之大,必须要求采取措施解决水化热及随之引起的体积变形问题,以最大限度的减少开裂。

”日本建筑学会标准(JASS5)的定义是:“结构断面最小尺寸在80cm以上,同时水化热引起的混凝土内最高温度与外界气温之差预计超过25℃的混凝土称为大体积混凝土。

”从上述两国的定义可知:大体积混凝土不是由其绝对截面尺寸的大小决定的,而是由是否会产生水化热引起的温度收缩应力来定性的,但水化热的大小又与截面尺寸有关。

我国有的规定认为,当基础边长大于20m,厚度大于1m,体积大于400m³时,称为大体积混凝土。

一般认为当基础尺寸大到必须采取措施,妥善处理混凝土内部所产生的温差,合理解决混凝土体积变化所引起的应力,力图控制裂缝开展到最小程度。

这种混凝土才称得上大体积混凝土。

2基础工程中大体积混凝土的特性2.1大体积混凝土的特点2.1.1特点大体积混凝土最主要的特点是以大区段为单位进行浇筑施工,每个施工区段的体积比较厚大,由此带来的问题是,水泥水化热引起的结构内部温度升高,冷却时如果不采取一定的技术措施,很容易出现裂缝,怎样防止基础工程中大体积混凝土的裂缝,在基础工程中是一个很重要的问题。

为了防止裂缝的产生,必须采取切实可行的技术措施。

如使用水化热比较小的水泥,参加适量的粉煤灰,使用单位水泥用量少的配合比,控制一次浇筑的高度和浇筑的速度以及人工冷却控制温度等。

在大体积混凝土设计和施工过程中,从事设计与施工的技术人员应掌握混凝土的基本物理性能,了解大体积混凝土温度变化所引起的应力状态对结构的影响,认识混凝土材料一系列的特点,掌握温度应力的变化规律。

在结构设计上,为改善大体积混凝土的内外约束条件以及结构薄弱环节的补强,提出行之有效的措施,在施工技术上,从原材料选择、配合比设计、施工方法、施工季节的选定和测温、养护方面,采取一系列的综合性措施,有效的控制大体积混凝土裂缝;在施工组织上,编制确实可行的施工方案,制定合理周密的技术措施,采取全过程的温度检测,只有这样,才能防止产生温度裂缝,确保大体积1混凝土的质量。

2.1.2 温差关于大体积混凝土的内外温差控制指标,国内至今还没有一个明确统一的标准。

根据日本的施工经验,一般控制在25℃以内,也有的工程控制在30℃获得成功。

随着我国建筑业的飞速发展,根据近年来的工程实践证明:混凝土的温升和温差与表面系数有关,单面散热的结构断面最小厚度在75cm以上,双面散热的结构断面最小厚度在100cm以上,水化热引起的混凝土内外的最大温差预计超过25℃,应该按大体积混凝土施工。

在全国很多一、二线城市以及大部分三线城市中,大批的高层建筑和高耸构筑物相继被建造。

这些建筑物的基础都采用了大体积混凝土,通过这些工程的实践,促进了大体积混凝土的施工技术的发展。

对大体积混凝土工程的研究,取得了不小的成就,主要是:2.1.3 设计在设计上,为改善大体积混凝土的内外约束条件以及结构薄弱环节的补强,提出了行之有效的措施。

2.1.4 施工在施工技术上,从选材、配合比设计、施工方法、施工季节的选定和测温养护等,采取一些综合的措施,有效地克服了大体积混凝土的裂缝。

2.1.5 管理在施工组织管理上,为了解决大体积混凝土一次浇筑量大的问题,在精心组织、协调指挥下才用了集中搅拌、罐车运输,泵送混凝土等技术。

3基础工程中大体积混凝土的施工3.1大体积混凝土对原材料的要求3.1.1水泥水泥水化热是大体积混凝土的主要温度因素。

因此水泥应选用水化热低和凝结时间长的水泥。

当拌制高强度等级的混凝土,必须采用硅酸盐水泥或普通硅酸盐水泥时,应采取相应措施延缓水化热的释放。

为避免大体积混凝土开裂,要尽量降低水泥用量。

有条件的地方应积极掺用粉煤灰或矿粉以降低水化热。

a.在满足强度和耐久性等要求的前提下,宜选用低热或中热的矿渣水泥、火山灰水泥,严禁使用安定性不合格的水泥。

b.由于大体积混凝土工程量大,水泥用量多,水2泥供应难以做到按施工要求的品种标号一次性进场,因此要加强水泥进场的检验和试配工作。

3.1.2外加剂在大体积混凝土中,如果采用各种外加剂以减少水泥用量,从而降低混凝土的温升是一种有效地方法。

大体积混凝土中常用的外加剂品种功能如减水剂、高效减水剂、缓凝减水剂以及其他多种功能如减水、缓凝、引气等复合剂。

在大体积混凝土中之所以采用缓凝型减水剂,主要目的在于延缓水泥水化热速度,推迟热峰出现时间,降低最高温度峰值并减少总的发热量,以减少混凝土因温度而引起的裂缝。

同时,由于延缓混凝土的凝结时间,有利于浇筑和捣实大体积混凝土时不致形成施工冷接缝,有利于延长振动时间或扩大振动范围。

3.1.3集料一般选用结构致密,并且有足够的优良集料(特别是粗集料),具体应符合相关标准规定。

除此之外结合大体积混凝土的特点,还应注意以下几个问题:1.3.1有害杂质。

拌制混凝土的集料要求洁净而不含杂质,以保证混凝土的质量。

砂石属于天然材料,长混入一些有害物质如云母、粘土、淤泥等。

特别是一些有机杂质、硫化物及硫酸盐,它们对水泥有腐蚀作,会降低混凝土的强度。

若使用混有碱活性反应的集料浇筑成混凝土后,在潮湿的环境中,经过一段时间的消化膨胀,便会发生开裂和剥落现象,并导致混凝土结构物的破坏。

集料品种和粒径要求。

砂子按其平均粒径和细度模数分为粗砂、中砂、细砂和特等细砂。

在大体积混凝土中宜使用粗砂或中砂。

石子有碎石和卵石。

当配合比相同时,碎石混凝土强度较高,抗裂性较好。

当混凝土抗压强度相同时,坍落度也相同时,卵石混凝土的水泥用量较少。

对于抗裂性有特殊要求的工程,当无碎石时也可以将卵石人工压碎。

石子按其最大粒径分为粗中细三类。

当所用的石子最大粒径较大时,混凝土的密实性较好,并可以节约水泥;但为了便于捣实,石子的最大粒径不得超过结构截面最小尺寸的1/4,也不得大于钢筋最小净距的3/4。

含泥量的要求。

在大体积混凝土结构工程中把含泥量作为一个突出的问题提出来。

因为过多的含泥量不仅增加混凝土的收缩,又会降低混凝土的强度,而且对抗裂性特别有害。

为此。

在施工中应严格控制标准规定,砂中含泥量<3%;石子<1%。
