The rainfall infiltration has a significant influence on the seepage field of landslip,which is the important reason of slope failure.Through the analysis of rainfall intensity,hydraulic grade and seepage discharge to the seepage field and the stability of soil slope,the paper got the inherent relation between the rainfall infiltration and slope instability.Based on the identical theory of equation of seepage field and the temperature field,it present a computer simulation of Fluid-solid interaction using A...
