基于一次逆可靠度法的边坡稳定性分析

摘要

本文从逆可靠度设计思路出发，解析并采用基于逆可靠度的边坡稳定性分析方法，对某边坡的安全系数进行了分析。结果表明，忽略参数的不确定性将会导致过高估计边坡安全系数。最后，讨论了可靠度水平与边坡安全系数的变化关系。%This article starts from the inverse reliability design ideas, analyzes and adopts the slope stability analysis method based on the inverse reliability, and carries out the analysis of safety coefficient for slope. The results show that ignoring par-ameter uncertainty wil lead to overestimate the slope safety coefficient. Final y, the author discusses the change relationsh-ip of reliability level and the slope safety coefficient.
