Abstract
Although landslide, slope failure, debris flow, rock fall, etc. are included in disasters caused by earth and sand, this report focuses only on slope failures. It is very difficult to discuss various soil engineering problems concerning earth and sand disasters in the Shikoku district from dynamic aspect. Therefore, this report is made focusing on perfunctory classification. As regards slope failures, there are natural and embankment (artificial) slope failures, but only natural slope failures are discussed in this report. The numbers of annually investigated areas in 4 prefectures in the Shikoku district and frequencies of failures for each geological group are tabulated for explanation. Transverse shape figure, longitudinal section, slope of ground level, land form where surface water and ground water tend to concentrate, etc. can be considered as factors for the occurrence of landslides. The relationship between those topographical factors and the frequency of failure occurrence is investigated. Failure of cut slope and the relation between rainfall and slope failure are outlined. Examples of rock fall disasters are introduced to point out the difficulty in predicting the occurrence of rock falls. 12 refs., 2 figs., 7 tabs.
