针对边坡稳定分析条分法存在的问题,在饱和-非饱和渗流不动网格有限元计算的基础上,用土体单元所受的渗透力代替其周边的孔隙水压力,达到利用渗流计算时的剖分网格和计算结果,直接连续进行渗流作用下的边坡稳定分析的目的,并采用数学规划中的单纯形法自动寻找最小安全系数.算例表明,该方法具有一定的实用性,并为考虑降雨等引起的饱和-非饱和不稳定渗流作用下的边坡稳定问题的分析提供了实用的工具.

In view of the problems existing in the slope stability analysis bar method, on the basis of the finite element calculation of the saturated-unsaturated seepage immovable grid, the permeability of the soil unit is used to replace the pore water pressure around it, so as to achieve the purpose of directly and continuously analyzing the slope stability under seepage by using the split grid and calculation results during seepage calculation, and automatically find the minimum safety factor by using the simplex method in mathematical programming. Examples show that this method has certain practicability and provides a practical tool for the analysis of slope stability problems under saturated-unsaturated unstable seepage caused by rainfall.
