초록

본 연구에서는 2011년에서 2014년까지 최근 4년간 국내에서 발생한 사면재해에 대한 현장조사를 수행하고 재해발생지의 지질 및 강우자료를 수집하여 국내 사면재해 현황 및 유발강우와 지질특성을 분석하였다. 분석 결과, 변성암 지역에서 가장 많은 사면재해가 발생하였으며, 사면재해 중에서는 토석류가 가장 많이 발생한 것으로 나타났다. 월평균 강우량이 높을 때 사면재해도 증가하는 것으로 나타났으나, 대부분의 사면재해는 최대시간강우량이 내린 이 후 일정한 시간이 지나고 발생한 것으로 나타났다. 또한, 전반적인 사면재해 발생횟수는 1개월 이상의 장기강우와 관련이 있는 것으로 분석되었다.

Triggering rainfall and geologic conditions with the state of slope hazard were investigated based on the field investigation and collected data on the slope hazard during the period between 2011 and 2014 in Korea. Analysis results showed that most of slope hazards occurred in metamorphic rock and debris flow was the most frequent type of slope hazard. Slope hazard increased when the higher monthly mean rainfall was recorded. However, most of slope hazard occurred when certain time elapsed after the moment of maximum hourly rainfall. Finally, more than one month of long-term rainfall was shown to be related to the frequency of slope hazard in the period.
