摘要
滑动面的确定是斜坡稳定性评价中的一个关键问题。基于变分原理 ,以土质斜坡为例 ,介绍斜坡潜在最危险滑动面的计算模型及解析表达式。并可直接求出斜坡的临界滑动面和对应的安全系数 ,无需假设滑动面和对斜坡进行条分 。
Determination of sliding surface is a key question in analysis of slope stability.Taking soil slope as an example,model and analytic formula of the most dangerous sliding surface are developed according to variational principle.From this principle,the critical sliding surface of soil slope and corresponding safety coefficients are directly found without assumption of sliding surface and conducting subdividing.This method can specifically be used in conditions of unknown sliding surface.
