Abstract

Abstract

On the basis of briefly analyzing the mathematical model for the saturation -unsaturated seepage flow of porousmedium, the selcetion method of such parameters affecting the seepage finite element calculation result as water and soilcharacteristic curve, hydraulic conductivity and capillary water pressure is discussed. In the end, the relative program isused to simulate the seepage field inside the excavation slope during rainfall, and the change law of the underground watertable, saturation of the slope, pressure head and seepage velocity of different positions inside the slope is analyzed. Thesimulation results are rather in agreement with the practical condition, which can provide the evidence for the stabilityanalysis of the slope.
