説明

A new Geographical Information System (GIS) - based slope failure hazard mapping method using Hayashi's quantification methods theory is proposed and applied in a slope failure prone area in Minamata City of Kumamoto Prefecture. In the past, Hayashi's quantification methods theory is often used in slope failure hazard mapping, however, the preparation of larger spatial data is very hard and the work efficiency is low and reliability of the results are doubtful sometime. In this research a series of GIS-based spatial data preparation method is proposed for quantification methods theory analysis and the results of the analysis results can be input into GIS to make hazard map directly. The application of proposed method on Minamata area shows that created hazard map has good agreement with real slope failure condition.
