（1）In the university, mathematics, physics, and chemistry are heavily emphasized throughout the engineering curriculum, but particularly in the first two or three years. Mathematics is very important in all branches of engineering, so it is greatly stressed. Today, mathematics includes courses in statistics, which deals with gathering, classifying, and using numerical data, or pieces of information. An important aspect of statistical mathematics is probability, which deals with what may happen when there are different factors, or variables, that can change the results of a problem. Before the construction of a bridge is undertaken, for example, a statistical study is made of the amount of traffic the bridge will be expected to handle. In the design of the bridge, variable such as water pressure on the foundation, impact, the effects of different wind forces, and many other factors must be considered.
（2）Passing sight distance is the minimum sight distance that must be available to enable the driver of one vehicle to pass another vehicle, safely and comfortably, without interfering with the speed of an oncoming vehicle traveling at the design speed, should it come into view after the overtaking maneuver is started. The sight distance available for passing at any place is the longest distance at which a driver whose eyes are 3. 5 feet above the pavement surface can see the top of an object 3. 5
feet high on the road.
Passing sight distance is considered only on two-lane roads. At critical locations, a stretch of four -lane construction with stopping sight distance is sometimes more economical than two lanes with passing sight distance. （3）Placing is the process of transferring the fresh concrete from the conveying device to its final place in the forms. Prior to placing, loose rust must be removed from reinforcement, forms must be cleaned, and hardened surfaces of previous concrete lifts must be cleaned and treated appropriately. Placing and compacting are critical in their effect on the final quality of the concrete. Proper placement must avoid segregation, displacement of forms or of reinforcement in the forms, and poor bond between successive layers of concrete. Immediately upon placing, the concrete should be compacted by means of hand tools or vibrators. Such compacting prevents honeycombing, assures close contact with forms and reinforcement, and serves as a partial remedy to possible prior segregation. Compacting is achieved by hand tamping with a variety of special tools, but now more commonly and successfully with high frequency, power-driven vibrators. These are of the internal type, immersed in the concrete, or of the external type, attached to the forms. The former are preferable but must be supplemented by the latter where narrow forms or other obstacles makes immersion impossible.
（4）That works must be completed to the satisfaction of the employer ,
or his representative ②, does not give the employer the right to demand an unusually high standard of quality throughout the works, in the absence of a prior express agreement. Otherwise the employer might be able to postpone indefinitely his liability to pay for the works. The employer is normally only entitled to expect a standard of work that would be regarded as reasonable by competent persons with considerable experience in the class of work covered by the particular contract. The detailed requirements of the specification will have a considerable bearing on these matters. （5）In an arch bridge the arch is the main structural member and transmits the loads imposed on it to the abutments at the springing points. The part of the construction above the arch ring when the roadway or railway is at a higher level than the crown of the arch is called the spandrel③.
Since steel and reinforced concrete are capable of taking tension, the arch rings can be very much thinner than in masonry construction. The braced spandrel bridge is usually constructed in steel, as is also the bridge where the roadway is supported by hangers from the structural arch. Another type of arched bridge is the stiffened tied-arch, which is often called a bow-string girder. In an archery bow the string prevents the bow from flattening out. In a similar manner, the road-supporting horizontal girders are made strong enough to absorb the arch thrusts, and therefore the reactions on the piers and abutments are vertical 。

短文翻译
1、The next step is the testing of the earth foundation on which the road is to rest. Engineers carefully study the soil to learn how solid it is, how much moisture it contains, and how well it drains. Then they decide how the soil should be prepared and packed to provide a good, sturdy foundation, or roadbed. They prescribe the thickness of the road layers, the size of the rocks in them, and the other materials that should be used.
While the testing is under way, a group of surveyors begin to measure the land to find out exactly how much work needs to be done and how much it will cost. Then the construction crew can finally move in.

2、Besides its ability to sustain loads, concrete is also required to be durable. The durability of concrete can be defined as its resistance to deterioration resulting from external and internal causes. The external causes include the effects of environmental and service conditions to which concrete is
subjected, such as weathering, chemical actions and wear. The internal causes are the effects of salts, particularly chlorides and sulphates, in the constituent materials, interaction between the constituent materials, such as alkali-aggregate reaction, volume changes, absorption and permeability.
In order to produce a durable concrete care should be taken to select suitable constituent materials. It is also important that the mix contains adequate quantities of materials in proportions suitable for producing a homogeneous and fully compacted concrete mass.
除了承受荷载的能力，混凝土的要求也将经久耐用。

混凝土的耐久性被定义为外部和内部原因导致的耐磨性。

外部原因包括环境和服务条件的混凝土遭受影响，如风化，化学作用和磨损。

内部原因是盐的影响，特别是氯化物和硫酸盐，在构成材料，组成材料之间的相互作用，如碱骨料反应，体积变化，吸收和渗透。

为了生产高耐久性的混凝土，应注意选择合适的材料组分。

同样重要的是，混合包含足够数量的材料配比适合生产均匀致密的混凝土。

3、Fresh concrete gains strength most rapidly during the first few days and weeks. Structural design is generally based on the 28 day strength, about 70 percent of which is reached at the end of the first week after placing. The final concrete strength depends greatly on the conditions of moisture and temperature during this initial period. The maintenance of proper conditions during this time is known as curing. Thirty percent of the strength or more can be lost by premature drying out of the concrete; similar amounts may be lost by permitting the concrete temperature to drop to 40 ℉or lower during the first few days unless the concrete is maintained continuously moist for a long time thereafter. Freezing of fresh
concrete may reduce its strength by as much as 50 percent.
新鲜混凝土获得大部分强度在最初的几天和几周。

结构设计是以28天强度，其中约百分之70是达到在第一周结束后放置。

最后混凝土的强度在很大程度上取决于在这个初始阶段的水分和温度条件。

在这段时间的条件称为养护。

百分之三十或更多的强度可以通过过早的失去了混凝土干燥；类似的量可以通过使混凝土温度降到40℉或在最初几天下除非混凝土连续保持潮湿，此后很长一段时间了。

新拌混凝土的冻可以减少多达百分之50的强度
4、The essential difference between the rigid pavement and flexible pavement is the manner in which they distribute the load over the subgrade. The rigid pavement, because of its rigidity and high modulus of elasticity, tends to distribute the load over a relatively wide area of soil; thus, a major portion of the structural capacity is supplied by the slab itself. The major factor considered in the design of rigid pavements is the structural strength of the concrete. For this reason, minor variations in subgrade strength have little influence upon the structural capacity of the pavement.
刚性路面和柔性路面的本质区别是它们将荷载对路基的方式。

刚性路面，由于其刚度和弹性模量高，往往会把荷载分布在相对宽的区域的土壤；因此，结构承载力的主要部分是由板本身。

主要因素在刚性路面的设计被认为是混凝土结构强度。

为此，在路基强度的微小变化对路面的结构能力影响不大。
