Abstract
Slope failure resulting from heavy rainfall on rail road lines is a common occurrence, making it essential to minimize the phenomenon in the interests of maintaining safe, punctual train operation. It is also necessary to evaluate disaster risk of individual slopes by considering the probability and potential cost of rainfall-related slope failure. We developed a method to evaluate disaster risk for slope failure using a risk estimation technique. This paper describes this developed method, and the method of priority determination for investment to prevent slope failure caused by intense rainfall using this developed technique.
