Abstract

Abstract

The initial soil moisture content distribution was one of the important factors that affect the moving down of wetting front. Traditional rainfall infiltration model only assumed that the initial moisture content was uniform and the situation of non-uniform was not taking into consideration. Based on the Mein-Larson rainfall infiltration model, this paper deduced a new landslide rainfall infiltration function by assuming the initial moisture content distribution linear with the increase of perpendicular to the direction of slope surface depth. It made up for the original model that only applied to the situation of uniforminitial moisture content distribution. The result showed that the initial moisture content distribution had large effect on the moving downof wetting front. In the case of initial moisture content was linear distribution, the greater the slope surface moisture content, the value of k which was the one of fitting parameters was closer to the zero, the faster the wetting front infiltrated. When the value of k equaled to the zero, the new model changed to the Mein-Larson rainfall infiltration model. It proved that the Mein-Larson rainfall infiltration model was a special case of the new model. Compared with the result of FEM, the results of the calculation model agree with that of FEM. It proved the reliability of the new model.
