摘要

通过分析鸡鸣寺滑坡等典型滑坡变形监测数据，总结了典型滑坡的变形破坏规律，作为边坡破坏的判别标准，并应用到基于强度折减和重度增加法的边坡稳定分析中。通过典型算例分析，建议以变形变化趋势为边坡破坏判别标准，并研究了强度折减法和重度增加法分析边坡稳定的可行性；较全面地分析了影响计算精度的各种因素。结果表明，采用的边坡破坏判别标准概念清晰、物理意义明确，界定清晰。相比较而言，强度折减法的可靠性和稳定性相对较好，适用范围较广。

Abstract

According to deformation observation data analysis of typical landsides

such as Jiming Temple landslide etc.

the deformation failure mechanism is summarized; and then the mechanism is applied to slope stability analysis as the failure criterion by adopting strength reduction method and gravity increase method. By classical instances

the failure criterion based on deformation trend is suggested; various factors effecting computation accuracy are also analyzed; and at the same time

the reliability and stability of previous methods are demonstrated. The result indicates that the failure criterion has a clear concept

special physical meaning and distinct definition for slope stability analysis. By comparison

the precision and reliability on basis of strength reduction method is better

and can be applied to most slope stability analysis.
