Abstract

Because of the infrastructure development in mountainous area close to urban area and the geographical characteristics of Japan such as the presence of many steep slopes, a number of slope disasters have been occurred at railway and road located in mountainous area. In this paper, the risk of slope disaster due to earthquake and rainfall is evaluated form the viewpoint of risk engineering. The object slope in this study is a slope at the north area in Shikanoshima, Fukuoka city damaged by the 2005 Fukuoka-ken Seiho-oki earthquake literally. The purpose of this study is to determine the priority area for countermeasure against slope failure in three areas having different failure depth predicted by the geotechnical profile in damaged area and to verify the effectiveness of selected countermeasure considering the supportive explanation in terms of cost benefit. Moreover, the risk representing as cost diminution is calculated considering the multiple effects of earthquake and rainfall.
