Therefore, the following works was conducted: 1 Setting up different types combination failure model of ice sheet interaction with semi-breakwater, and considering different actual conditions of crushing, bending and bucking failure in the process of ice pileup when ice sheet acts on the semi-breakwater; 2 Applying analysis of non-continuous transmutation for the numerical simulation. This method is a new numerical analysis method of simulating mechanics response of dispersoid, it has a broad application prospect for the simulative questions of ice sheet moving, deforming, breaking and circumvolving after ice sheet occur pileup.

The results indicate that the main erosion type is sheet ero-sion at the beginning of the rainfalls, and serious erosion happens after rill erosion appears. Accumulated sheet and rill erosion amount increases with the rainfalls time. The percentage of sheet erosion amount decreases and rill erosion percent-age increases with time. At the end of the rainfalls, the total rill erosion amounts are 4.3 and 5 times more than sheet ero-sion.

研究结果表明，降雨初期坡面以面蚀为主，细沟出现后，坡面侵蚀将加快加剧；随着降雨时间的延续，累积面蚀量和细沟累积侵蚀量都将逐渐增加，后者的增加速率大于前者，面蚀所占总侵蚀量的百分比随降雨时间呈曲线形式逐渐递减，细沟侵蚀则逐渐增加；试验结束时细沟侵蚀量分别为面蚀量的4—5倍。

Quantitatively studying on the change of accumulated sheet and rill erosion amounts.Sheet erosion rate firstly gradually increased, then rapidly increased and finally remained stable with the rainfalls time, but the rill erosion rate increased more quickly than sheet erosion rate and the value of rill erosion rate was higher than of sheet erosionrate.
