岩质边坡结构面实用分类方法研究
|
摘要
已有岩体结构面分类方法多数为定性分类,很少定量给出结构面力学参数,难以在岩土工程设计中应用。而目前各种规范采用的实用分类方法在参数取值及分类指标描述等方面仍需进一步完善。在广泛收集公路、铁路、水利水电、城市建筑边坡岩体结构面试验成果的基础上,通过分析整理,对国标《建筑边坡工程技术规范》(GB 50330-2002)结构面分类方法进行完善和补充,提出了相应的修正意见,提升了该分类方法的科学性与实用性,使岩质边坡设计更趋合理。研究成果可为岩质边坡工程技术规范修订提供参考。
At present,many classification methods of discontinuities in rock slope are the qualitative classifications,few can give the mechanical parameters qualntiatively.It is difficult to apply them to the design in rock and soil engineering.The practical classifications in various kinds of Codes should be improved in choosing parameters and describing indexes.In this paper,the classification method of discontinuities in National standard Technical Code for Building Slope Engineering(GB 50330-2002) is improved based on analyzing the experiment results of the discontinuities in rock slope of highway,railway,water conservancy,hydroelectric power and city construction.The modification ideas are proposed to improve its practicability and to make the design of rock slope more reasonable.The study result in this paper can provide references to revising the technical codes of rock slope engineering.
