摘要
根据地震对边坡的作用不同 ,地震边坡失稳分为 :惯性失稳和衰减失稳 .惯性失稳的分析方法有拟静力法、Newmark滑块分析法、有限元方法及概率分析法等 .而衰减失稳的分析方法有流动破坏分析法和变形破坏分析法等 .本文对这些分析方法的发展、应用及特点进行了综述 ,提出了地震边坡分析中主要研究内容。
On the basis of the different seismic effects,seismic slope instabilities may be grouped in to two categories:inertial instability and weakening instability.A number of techniques for the analysis of inertial instability have been proposed,such as pseudostatic analysis,Newmark sliding block analysis,stress deformation analysis and probabilistic analysis.Weakening instability can be divided into flow failures and deformation failures.The development,application and characteristic of those methods are summarized in this paper.And the main content,the existing problem and trend to the seismic slope analysis are proposed.
