【摘要】纳米MgO具有不同于传统固化剂的独特性质,在土体固化方面受到了广
泛关注。

以纳米MgO和石灰综合固化的黄土为研究对象,通过无侧限抗压强度试验、回弹模量试验、承载比试验,对不同固化剂掺量和养护龄期的固化黄土试样的
力学性能进行了研究。

结果表明:石灰质量分数为3%、纳米MgO质量分数为
0.3%~0.6%的固化黄土可兼顾经济、环保及工程性能等多重要素;随着养护龄期的增长,无侧限抗压强度、回弹模量及承载比均逐渐增大,养护前期(14~60 d)固化黄
土力学性能指标的增长速度快于养护后期(90~180 d)。

通过对试验数据的回归拟合,建立了无侧限抗压强度、回弹模量和承载比的力学指标预测模型以及它们之间
的关系,为纳米MgO和石灰综合固化黄土路基工程的设计和质量评估提供了参考。

基于XGBoost模型岩体可爆性研究

基于ＸＧＢｏｏｓｔ模型岩体可爆性研究收稿日期：２０２３－０８－０３；修回日期：２０２３－１０－２５基金项目：国家自然科学基金项目（５２２６４０１９，５１８６４０２３）作者简介：吴凌峰（１９８６—），男，工程师，从事地下采矿工程研究工作；Ｅｍａｉｌ：４０３３０２９７４＠ｑｑ．ｃｏｍ通信作者：周宗红（１９６７—），男，教授，博士，从事采矿与岩石力学教学与研究等方面工作；Ｅｍａｉｌ：ｚｈｏｕ２００５１００１＠１６３．ｃｏｍ吴凌峰１，周宗红２，孙　伟１（１．金平长安矿业有限公司；２．昆明理工大学国土资源工程学院）摘要：岩体可爆性是衡量岩体爆破难易程度的一个重要指标，准确对岩体可爆性评价能够为合理爆破设计提供依据。

选取岩石密度、单轴抗压强度、岩石抗拉强度、岩石脆性指数、动载强度和完整性系数等作为岩体可爆性数据集的指标，采用Ｚ－Ｓｃｏｒｅ方法标准化岩体可爆性数据集，消除量纲对模型预测影响，分别采用朴素贝叶斯、支持向量机和ＸＧＢｏｏｓｔ模型进行岩体可爆性分级，结果表明：采用ＸＧＢｏｏｓｔ模型能够准确评价岩体的可爆性，为岩体可爆性评价提供一种新的方法。

由于矿山爆破自身存在不确定性、复杂性和多变性等，目前国内外对于岩体可爆性尚未达到统一共识。

因此，亟须探索一种方法进行岩体可爆性评价。

国内外学者对岩体可爆性展开研究，常用的分级方法包括单一指标普氏分级、勒诃谢达洛夫法和邦德法；多指标苏氏分级、库图佐夫分级和神经网络分级等。

单一指标分级多为早期岩体可爆性分级研究，岩体可爆性与岩石本身性质和爆破工艺相关，故单一指标无法有效反映岩体可爆性，近些年多指标研究被学者们广泛关注［１－３］。

NBOG_BPG_2009_3

NBOG’s Best Practice Guideapplicable for ⌧ AIMD, ⌧ MDD, and ⌧ IVDD 2009-3 Guideline for Designating Authorities to Define the Notification Scope of a Notified Body Conducting Medical Devices Assessments1 IntroductionNANDO [1], published and maintained by the European Commission, is an electronic register that enables interested parties to consult regulatory information of Notified Bodies (NBs). The NANDO register contains scope information of Notified Bodies under the New Approach Directives. Up to now the information provided by Member States is not precise enough to allow the comparisons necessary to promote a free competition between Notified Bodies in the medical devises area.In particular in the medical devices sector, identical designation information appears in the register in a broad variation between NBs. Different Designating Authorities (DAs) use different expressions when they sign up for designation of their NBs. In some Member States (MS) the DAs submit the designation information, the so-called scope, by just take reference to one of the medical devices directives. Other MS try to define and submit a detailed scope according to the existing and monitored competence of their NBs. This can end up in very exhaustive information per directive and NB.The NANDO information provided to interested users like manufacturers, Designating Authorities and Authorities responsible for market surveillance, required an improvement. For Designating Authorities, this guideline aims to describe medical devices scope expressions for Notified Bodies in a comparable and harmonized way.2 Scope of the documentThis guideline provides scope expressions, describing activities of NBs to demonstrate medical devices competence for their notification in the NANDO register. The expressions are defined per directives for DAs to achieve harmonized listings of NBs skills. In addition application for modifications can be submitted in a uniformed way to the European Commission responsible for maintenance the NANDO register.This document is applicable to products according to Directive 93/42/EEC (MDD) concerning medical devices, Directive 90/385 (AIMDD) concerning active implantable medical devices and Directive 98/79/EC (IVDMDD) on in vitro diagnostic medical devices.3 Concept for defining scope expressionsWith this document a collection of existing relevant medical device information has been considered. This guideline takes reference to:– NANDO register [1]– The three main medical devices directives (MDD, AIMDD, IVDMDD)– All modifying or implementing directives to the three main directives– CEN Technical report CEN/TR 15133 : 2005 "Nomenclature – Collective terms and codes for groups of medical devices" [2]– The Designating Authorities Handbook [3]As explained in the Guide to Using [4], the NANDO register contains three levels of information per Directive. With one exception (89/106/EEC) this is handled in the same way for all NBs in all Directives, including the medical devices sector.The list of the register with the description of the tasks performed for one NB and one Directive contains three columns, reflecting the three different levels. They are named “Product families”, “Procedures” and “Articles/Annexes”. Whereas for the level of the “Product families” neither a structure nor a specific wording exists, the information for the two other levels is well defined. This limits automatically any kind of harmonization to the Level of “Product families”. Due to the fact that the NANDO structure should not be modified for individual Directives, particular attention was given to an understandable wording with an adjusted structure of scope expressions.Scope expressions as they are recorded in the NANDO list have to correspond evidently with the competence of a NB. This competence shall be assessed, by taking reference to the DA Handbook [3].At the end a clear statement with regard to the scope of the designation of a NB should be given.

With such a demand there is strong requirement for a clear understanding of the content of each expression. To minimize definitiondiscussions and to take in consideration the helpful development of the Technical Committee CEN/TC 257, this guidance uses the collective terms of the technical report CEN/TR 15133 [2] as a source of definition. The report has been prepared to specify terms associated to common technologies, similar manufacturing procedures, similar medical procedures, common materials and specific risk – associated considerations of medical devices. According to the report, these terms are appropriate for providing general groupings to meet particular requirements, such as to identify the range of skills and general technological abilities for which a NB has been approved.Considering the intention of the mentioned report, the lists contain definitions by using or/and grouping collective terms. With such definitions, each list has a manageable quantity of scope expressions and the interested NANDO users have the chance to understand unambiguously the single expressions.The technique of grouping collective terms to scope expressions can be explained with the following example:– The MD 0204 scope expression “Non-active soft tissue implants” is defined by grouping collective terms together. The group contains terms, which could be brought in conjunction with the particular device.– These collective terms can be for “soft tissue implants” (not exhaustive): CT:005, CT:091, CT:234, CT:088, CT: 165, CT:179, CT:143, CT:189, CT:185, CT:160, CT:140, CT:044, CT184, CT:208, CT:207, CT:212, CT:201, CT: 237.Since the NANDO register distinguishes between directives, separate lists for each of the three directives (MDD, AIMD and IVDD) have been set up. The architecture of the lists differs between the directives.The titles support the grouping and formation of structured scope expressions. This results in an improved overview.To have a clear identification and allocation, each expression is assigned with a code. This code can be used as a reference for electronic transmission of data. The codes, ending with values to whole hundreds, are reserved for group titles, e.g. code “AIMD 0100” stands for the title “general active implantable medical devices”. The different expressions within the groups are sequentially numbered. But only the listed terms under each title, and not the titles themselves, are relevant expressions for demonstrating the NB’s competence. The prefixes take reference to the relevant directive and specialities, e.g. “MDS” for “specialities”.The listings have been set up as a consensus result of NBOG. To ensure future consistency of the NANDO data entries, any change of or addition to the scope expressions is subject to NBOG endorsement.4 ImplementationDesignations of new NBs shall take into account the scope description as defined above. DAs forward this information to the European Commission responsible for maintaining the NANDO register as defined within the established electronic notification system.The European Commission will implement the new structure in NANDO rapidly. The DAs shall change the scope of their existing NBs until 21 March 2010. Up to this time, both the new and old NANDO structure will be accessible in parallel.References Directive 93/42/EEC, Directive 90/385/EEC, Directive 98/79/EC[2] CEN/TR 15133 : 2005 "Nomenclature – Collective terms and codes forgroups of medical devices"Keywords Designating Authority, notification, Notified Body, scopeDate of issue March 2009。
