Abstract
The changes in climate all over the world have brought various natural disasters such as flood, drought and so on. In Japan various types of slope failures due to rainfall often occur in the rainy season. Therefore Kitamura et al. have proposed a prevention system of slope failures due to rainfall. In this paper, the soil tank tests are carried out in order to analyze the mechanism of slope failure due to rainfall. The pore-water pressure in the soil is measured by the tensiometers and pore-water pressure sensors. The experimental results are compared each other, and the seepage and failure behaviors of Shirasu slope during rainfall are analyzed.
