Effect of the rainfall on slope stability

Abstract

     In recently, number of slope failures with a large-scale have occurred in the mountain area and caused a lot of human lives and properties lost. The slopes failures are usually occurred after heavy and long duration of rainfall. However, up to now the studied of the effect of rainfall on slope stability have not been extensively studied. This paper presents some results of the rainfall induced slope failures. An example to calculate factor of safety for particular slope in the centre of Vietnam under rainfall conditions is presented. The results of this study are a foundation for explanation of instability of the slope due to rainfall.
