Abstract

The Hiegaesi landslide, a long-runout landslide triggered by heavy rainfall with travel angle of 11.2° was investigated. In an observation pit dug in the middle part of the landslide deposit, the sliding zone just above the deflected rice plants was observed, and it was confirmed that grain crushing occurred in the sliding zone. The triggering and sliding mechanisms then were investigated by undrained ring-shear tests in laboratory. The apparent friction angle obtained in this test was 8°. It is concluded that, during the sliding in rice paddy, the undrained shear strength of the soil layer itself, mainly influenced the high mobility of the landslide.
