Research Abstract

To understand the mechanism of landslides occurring during abnormal weather condition and then to develop a new evaluation approach of landslide hazard, we made field survey of some landslides recently occurred in Japan, set up a new monitoring system on a landslide, and also did laboratory tests. The main results could be summarized as follow. 1) Lowered air pressure during typhoon failed to reactivate a landslide, but affected the movement after the sliding was triggered by rainfall. 2) Localized shearing on unsaturated soil layers may result in the moisture transfer within the soil layer and then affect the shear behavior or stability. 3) Water repellency of the soil layer may greatly affect the initiation and movement mechanism of shallow landslides.
