摘    要:建立在土坡饱和-非饱和渗流计算和土坡非饱和稳定性计算基础上提出了稳定系数降雨容量的概念,将降雨条件下土坡的稳定系数仅仅和降雨容量系数相联系。列出了稳定系数-降雨容量回归方程,通过对比知,稳定系数和降雨量、持雨时间有很好的相关关系。降雨容量系数的使用能迅速获得不同的降雨组合下土坡的稳定系数,同时也能利用这个概念对土坡的危险气象条件进行预测、预报。

关 键 词:非饱和土  土坡稳定性  稳定性分析  计算方法

Abstract:In this paper,based on soil slope saturated-unsaturated seepage calculation and soil slope unsafurated stability analysis,rainfall volume concept is put forward,soil slope stability coefficient is only related to rainfall volume coefficient,and the stability coefficient-rainfall valume regression equation is listed,through comparison,it can be seen that good correlation exists between the stability coefficient and rainfall together will raining duration.By use of rainfall volume coefficient,soil slope stability coefficient under different raining combinations can be quickly obtained.This concept cna be used to predict dangerous climatic conditions of soil slope.
Keywords:unsaturated soil  soil stability  computational method
