The Finite-element Analysis of Characteristics of Soil Slopeseepage Field Change in Continuous Rain Condition
A numerical model is built by Finite Element Software,discussed the effect of rainfall on slope pore water pressure,volatile water content and depth of infiltration in continuous rain condition.The result indicated that when the rainfall intensity and rainfall duration reach a certain condition,the ground water table rises slowly,and mostly,the spill points of ground water locate in the foot of slope.The slope section appears three pore water pressure divisions:transient saturated zone,negative pressure region and hydrostatic pressure area after the rain.
