Abstract
Surface failure caused by snow melt occurred in April, 1997, on the Kohirasawa, Yunotani village, Niigata prefecture. In this study, a model for predicting surface failure caused by snow melt are proposed using the heat balance method, saturated unsaturated infiltration analysis method and infinite slope stability analysis method. And then this model is applied to the mountain slope in Kohirasawa to consider the process and mechanism of surface failure caused by snow melt. The results obtained are as follows (1) Snow and safety factor distribution obtained by numerical computation are consistent with actual distribution .(2) The effect of snow melt to the surface failure is that the water is supplied to the surface layer constantly and it gets ground water level high easily by rainfall.
