Abstract

This paper presents a framework of risk management of rockfall using real survey data. Hida area located in Gifu prefecture in Japan is selected as a target area. In the evaluation process of rockfall provability, relative probability is calculated based on results of the survey data using the logistic regression analysis. Then, absolute probability is calculated using history data of occurrence of rockfall in the target area. In the evaluation process of the economic loss, road closure induced by rockfall is considered. Direct and indirect losses are taken into consideration. A trial calculation with different strategies were conducted based on calculated risk, and then it was summarized the obtained results are useful information for rockfall risk management.
