사면붕괴에 따른 피해도 추정을 위한 토사 충격력 평가

초록

Global climate change leads to natural disasters. Especially slope failure and debris flow etc. are main factors to make bad effects to railroad or highway. In design stage, impact energy by fallen rocks is calculated for fence and retaining wall but, no specification is existed for soil impact force by slope failure and debris flow. In this study, real scale tests are executed to evaluate soil impact force and compare to formal empirical equation. New equation for soil impact force with variation of distance between a slope and fence, variation of a slope angle is suggested and it is possible to consider impact force in fence and retaining wall design.
