Abstract

Abstract

The effect of the rainfall patterns is often ignored in studies of the relationship of rainfall versus shallow stability of landslide. This paper takes four representative rainfall patterns including uniform, delayed, advanced and central ones as the object of study to explore the effect of the rainfall patterns on the height of ground water, based on the hillslope hydrological model proposed by Rosso. And then the infinite slope failure model is applied to establish the stability calculation model for shallow landslide, and the effect of the rainfall patterns on shallow landslide stability is analyzed. Results show that rainfall patterns have strong effect on the stability of shallow landslide, with the delayed rainfall having the lowest safety factor for shallow landslide, followed by uniform rainfall, then central rainfall, and lastly the advanced rainfall. It is found necessary to consider the effect of rainfall patterns for determining of the critical rainfall and analyzing of the susceptibility of shallow landslide in a region.
