The working technology and the design way were continuously improved and perfect . but there is n ' t unified and explicit design way and standard to be used by designer , there are different views on the design theory too 直到2000年底，建设部才通过了灌注桩后压浆加固的施工规范，但是还仅仅停留在行业规范的标准上，还不够完善和全面。
The concrete construction specifications currently in effect regarding the standard for evaluation of homogeneity of construction quantity of concrete are most applied to middle and lower strength concrete , but not to high strength concrete 现行混凝土施工规范对混凝土施工强度匀质性评定标准，多适用于中低强度混凝土范围，不适用于高强混凝土。
From beginning of establishment , sunriser creates modern management system , enhances professional and efficient team and continuously involves in standard and strict management for decoration industry 自创建之日起，公司严格建立健全规范的现代装饰企业管理制度，组建打造一支专业化、高素质的装饰设计施工队伍，并持续致力于装饰行业的正规化管理及施工规范建设。
At home , research on the external prestressing technique is not much , and studies on mechanical performances of this kind of structure system is quite limit , meanwhile engineering practices are few , and the corrresponding specifications and codes for design and construction are lacking , all of which lead to advantages of the system are not sufficiently exhibited 我国体外预应力技术的研究工作开展相对较少,对体外预应力结构的力学性能的研究还非常有限,工程实践不多,缺乏相应的设计、施工规范和规程,不能充分体现这种结构体系的优越性。
3 . production craftwork of main prefabrications and construction technics of the whole system are described in this thesis and the stress is put on the construction methods of the in - situ sandwich floor boards and the design of its supporting system , combined with current relative construction criterion and the special traits of the system , providing construction reference for the system 结合现行有关施工规范及体系的具体特点，讨论了主要预制件的生产工艺和体系的施工工艺，重点阐述了现浇双向密肋夹芯楼盖的施工方法，详细介绍了该类楼盖施工支撑体系的设计、选择和组装，为该类体系的施工提供参考。
In 1994 , the criterion of highway safety appurtenance design and construction was issued in our county , it makes a specific provision on design and use of several guardrails , but much of its content follows foreign experience . so we must enhance our knowledge on safety performance of rigid guardrail . it is necessary for us to study the process and response of vehicle impacting guardrail and to accumulate technical data for guardrail design 1994年我国颁布的《高速公路交通安全设施设计及施工规范》 ，对包括刚性护栏在内的各类护栏的设计和使用都作了明确规定，但其大部分内容均为沿用国外经验，因此，国内对于刚性护栏安全性能的研究仍是一项有待加强的工作，有必要针对我国的具体情况，研究汽车冲撞护栏的过程与反应，为我国护栏设计积累必要的技术数据。
According to the subentry coefficient method for calculating anti - sliding and anti - inclining stability recommended by the code for design and construction of port and waterway revetment engineering , the cross section of a gravity revetment is optimized by using the complex method considering the effects of ship waves 摘要采用复合形优化法，结合《港口及航道护岸工程设计与施工规范》中推荐的抗滑、抗倾稳定的分项系数计算方法，并考虑了内河航道船形波等作用的影响效应，对重力式护岸断面进行了优化。
To control the settlement of roadbed , the degree of compaction regulated by current criterion is not enough , the mechanics parameter of filler compacted - - deformation parameter should be considered and dual control criterion should be put in practice . to get upper deformation parameter of xigeda stratum filler , the percentage of mudstone should be controlled . the thickness of filling layer regulated by current criterion can be increased if the compaction car has proper function 通过此次研究，获得了对路堤变形问题的新的认识，即为了控制路堤的沉降变形，不仅应满足现行规范中规定的压实度标准，还应该引入填料压实后的力学参数? ?变形模量值标准，实行双重控制标准，而对于昔格达地层这种混合填料，为了获得较大的模量值，应该控制填料中泥岩的含量；现行公路路基施工规范中对路堤填筑时分层填筑厚度的规定值，在压实机具功能满足的条件下，可以适当提高。
At present , however , there are no code for design and construction of csbcs , and there are many problems remain to be studied about the application thereof , such as the interaction between csbcs and soil , overall stability of csbcs , and effect of the thickness of cs ( corrugated steel ) on csbcs , and the application of cs to middle or large bridge , and so on 然而，目前尚无关于波纹钢板生产标准和波纹钢板结构设计、施工规范或规程；同时，波纹钢板桥涵应用还有许多问题有待于进一步研究，如波纹钢板桥涵和土的共同作用问题，波纹钢板桥涵的稳定性问题，波纹钢板厚度对结构的影响，波纹钢板能否适用于中、大跨径的桥涵等等。
So the paper is also a conclusion of the construction of cdma 1x network and the development of valueadded data services . based on related cdma network design , construction discipline of china unicom and requirement analysis of sichuan unicom " development , the paper analyses and designs the packet switching network project , the no 2 construction project of sichuan union 本文依据中国联通公司相关的cdma网络设计、施工规范，根据四川移动通信发展的需求分析设计了中国联通四川分公司cdma二期工程建设的分组数据交换网的建设和实施方案，该设计方案在专家组的评审通过后已经在四川省各地市实施。
