Title: Numerical Simulation of Unsaturated Soil Slope Stability Coupling under Rainfall
Abstract: Rainfall is one of the main factors that influence the stability of slope.Rainfall infiltration will cause soil saturation changing and further influence pore water pressure and medium permeability coefficient.Considering the influence of rainfall infiltration,and based on two-phase medium coupling of unsaturated water and soil,this paper carries out numerical simulation on soil slope under constant rainfall with strength reduction finite element method according to rock soil saturated-unsaturated infiltration theory.It also analyzes the changing rule of slope displacement,pore pressure and safety factor during rainfall at different period of time and different rainfall intensity.
