Abstract

We performed a hydraulic analysis based on the wetness index of talus slopes in Jungsun, Gangwon province. We estimated the relation between the degree of development of the temporary water system, and talus topography and distribution. We also assessed the distribution of talus based on a map of the wetness index. We divided areas of tallus into stable and unstable types, and estimated the size, distribution and shape-preferred orientation of clasts. We performed numerical simulations of rockfall events to assess the optimum location of rockfall barriers upon talus slopes.

강원도 정선 지역에서 테일러스가 발달하는 사면의 습윤지수를 산정하여 강우시 한시적으로 형성되는 수계와 테일러스의 관계를 고찰하였고, 습윤지수 도면을 통하여 테일러스 분포 특성을 파악하였다. 또한 테일러스 사면을 안정형 테일러스와 불안정한 테일러스 형태로 구분하여, 역의 크기, 분포, 퇴적 방향 등의 야외 노출 상태를 기재하였다. 테일러스 사면에 대한 낙석시뮬레이션을 통하여 테일러스 사면에서의 낙석방호시설의 적정 설치 능력 및 위치에 대한 연구를 수행하였다.
