Abstract
There are more than ten thousand places in Japan which are in danger of landsliding, and they are mostly distributed in Hokuriku and Shikoku districts. Shikoku is a district which suffers many typhoon disasters, and the rate of ground disasters among the typhoon disasters has been getting higher in recent years. Reports are made on the general characteristics and soil mechanical properties of fractured zone landslides, which are the majority of landslides occurred in the Shikoku district. Most of the landslides in the Shikoku district occurred in Sanbagawa zone, south of the central tectonic line, and little landslides occurred in the granite zone in the Inland Sea area. Although rocks in landslided areas are fractured, little progress is observed for clay formation. The scales of the landslides are from several tens of meters to over 1km, with the average of about 20m, in length and from 200 to 300m in width. Although some of them have the depth of more than 50m, the average is about 20m. Descriptions are made on the relationship between the movement of landslide and rainfall, strength constants of cohesive soil in the slid strata, and the variance in the dynamic constants of cohesive soil in
