摘要
本文从地下结构可靠度分析必须涉及到的几个主要方面,即岩土参数的概率特征;作用效应的随机分析;针对岩土工程特点的可靠度指标计算方法等介绍了国内外,主要是国内的若干研究成果。还介绍了铁路等部门结合修订隧道设计规范开展可靠性研究的动向。
In this paper, from several aspects involved in underground structure reliablity analysis such as probabilistic characteristic of rock and soil parameters and random analysis of action effect,some research results both at home and abroad are introduced,aimed at reliablity index calculation method of geotechnical engineering properties. The tendence of reliabilty research carried out in railway and other departments in accordence with the revision of tunnel design specification is also introduced.
