ABSTRACT

This is a study about the analysis of cause of landslide and rainfall characteristics for the slope face and debris flow occurred in Hoengseong Gangwon Province in the year 2013. From the results of field test for the one artificial slope face and two mountain area, it was found that thinning-out trees laid everywhere in mountain area interrupted the drainage and catched rain water. Therefore, it affected slope failure. Furthermore, slope failure was occurred because of no drainage facility and compaction failure in somewhere. By the way, the maximum rainfall intensity, day rainfall amount, and accumulated rainfall amount were exceeded the limit of landslide watch in Korea Foreset Service. It could be determined that sharp slope area was collapsed by heavy rain and saturated by long term rainfall.
