낙석대책공법 비용편익분석기법 개발

Abstract
Rockfall mitigation methods have been widely constructed along railway lines but aren't estimated with any economic analysis methods up to now. Therefore, this study applied a benefit-cost analysis to rockfall mitigation method to determine whether it is indeed an economically efficient construction. The Benefits were estimated based on data collected from disaster history, and included three types of benefits that are originated by reduction of train accident, train delay and rockfall removing cost. The costs included both construction cost and the maintenance cost of the selected method. This analysis could clarify the investment effect of rockfall mitigation method that would be built at rockfall prone slope.
