| Outline of Final Research Achievements |
A lot of slope failures were occurred during rainy season in Japan. In order to determine reasonable evacuation criteria for rainfall-induced slope failure, an quantitative estimation system about slope stability for rainfall-induced slope failures was proposed in this project. The system consists of ground survey, slope monitoring techniques and numerical simulations. Firstly, the relationships among precipitation, pore-water pressure in unsaturated ground and slope failure were discussed using results obtained from laboratory experiments and field measurements. the measurement techniques on evaporation from ground surface and pore-water and pore-air pressure in unsaturated ground were then proposed. A slope stability analysis method by considering unsaturated seepage force in unsaturated slope was also proposed.
