粘性土坡稳定性分析的最小虚重度法

METHOD OF MINIMUM FALSE UNIT WEIGHT FOR ANALYSING STABILITY OF CLAY SOIL SLOPES

基于粘性土坡将沿某一圆弧面产生滑动破坏的最一般假定，并在土坡稳定性分析常用基本假定的前提下，引入土坡滑动体虚重度的概念，建立了粘性土坡稳定性分析的最小虚重度法及与其相对应的确定最危险滑动面的计算公式。

ased on the common assumption that clay soil slopes will split and slide alony some circular surfaces and other assumpfions often used for analysing soil slopes,an idea of false unit;weight of slidiny soil mass is introduced, and then the method of mininum false unit weight for analysing the stability of clay soil slopes is established some corresponding formulas for determining the most dangerous sliding surface are deduced.
