Abstract
In recent years, intensive rainfall has occurred with increasing frequency due to climate change, and has had an effect on slope failure. Such rainfall is intense and occurs repeatedly. During the rainfall, most of the water flows along the slope face, but some seeps into the soil, inducing surface failure of the slope. In this study, the infiltration characteristics of intensive rainfall are analyzed under various conditions to evaluate its effect on slope stability, using the Finite Element Method. As a results of this study, the shorter rainfall period and the more rainfall repetition number, the bigger effect of rainfall infiltration is and although the duration of rainfall is short, infiltration effect of rainfall is necessary to be considered on slope stability.
