Simulation analysis of landslide rainfall infiltration based on temperature field

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 Adina finite element program.The changes of seepage velocity and flow rate are proposed under the condition of different rainfall intensity.The front edge of the landslide with obvious seepage and hydraulic gradient could induce great increase of seepage failure,seepage flow velocity changed obviously in the slide zone,the direction of percolation flow are studied.Above all,this paper made the researches on the rainy inducing factor and the seepage field of slide zone to offer effective references for further researches on this issue.
