摘　　要：稳定性分析是岩土工程中一个很重要的方面,其分析方法有多种。而极限分析理论是一种行之有效的稳定分析方法,它能明确得出垮落载荷无需逐步进行弹塑性分析,其定理包括上限定理和下限定理,准确解位于在上下限之间。文中阐述了极限分析理论的发展和极限分析在隧道、边坡稳定性经典问题中的应用,介绍了极限分析理论常用的计算方法,最后说明了经典极限分析理论存在的主要问题。Stability analysis is an important aspect in geotechnical engineering,with many analysis methods.Thereof limit analysis theory is an effective stability analysis method,which can define collapse load clearly without carrying out elastic plasticity analysis progressively.Its theorem includes upper bound theorem and lower bound theorem,hence able to seek for the precise solution between upper bound and lower bound.This paper describes the development of limit analysis theory and its application in solving the typical problems of tunnel and slope stability,introduces the common calculation method for limit analysis theory,and finally gives a description of the major defects in using classical limit analysis theory.
