“…Ohhira et al (1962) and Nakano (1967) investigated the mechanical properties of tertiary sedimentary rocks (mudstone or shale) sampled from the bed rock of the sliding area, tested the slaking behavior in the laboratory, and suggested that weathering was one of the main factors for landslides in the tertiary mudstone area. Matsuo (1962) investigated the landslide which occurred at Kashio near Nikawa Station of the Keihanshin Express Imazu line on 13 July, 1951 and suggested that a decrease in calcium ions in the pore water due to excessive rainfall resulted in a reduction in the safety factor of the slope. Kishimoto (1962) carried out an unconˆned compression test on undisturbed soils sampled from the potential slip plane to investigate the failure mechanism for the heterogeneous layered slope.…”

Fig. 1. Mechanism of rainfall-induced slope failures 955SOILS AND FOUNDATIONS Vol. 50,No. 6,[955][956][957][958][959][960][961][962][963][964] Dec. ABSTRACTThe many recent slope failures due to heavy rainfall have been accompanied by signiˆcant loss of life, and massive damage to infrastructures and heritage. Many studies have been done to investigate the mechanism of rainfall-induced slope failures and establish a prevention system for slope disasters. In this paper, the state-of-the-art research works on slope failures due to rainfall published in the journal of Soils and Foundations (S&F) during the latest 50 years are reviewed and summarized. This report is written with the perspective that knowledge of unsaturated soil mechanics is necessary to elucidate the mechanism of rainfall-induced slope failure.
