- Abstract:
-
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.
