Abstract

Landslide researches are divided to a method of interrelationship for various factors, method of predicting landslide possibility, and method of estimating landslide risk which are occurring landslides in the natural slope. Most of landslides occurred in natural slope are caused by a heavy rainfall in summer season. Weathered soil layer located in upper side of rock mass was occurred. As well as, they are announced to have an influence to geometry, geology, soil characteristics, and precipitation in the natural slope. In order to investigate and interpret the variety of landslides from field investigation to risk analysis, landslide analysis process due to geotechnical and geological opinions are systematically demanded. In this research, the study area is located in Macheon area, Gyeongsangnam-do and performed the landslide investigation. From the results of landslide investigation and analysis, optimized standard model based on natural landslide is proposed to high technical method of landslide investigation and interpretation.

산사태연구는 산사태를 발생시키는 여러 인자들의 상호관계를 규명하는 방법, 확률론적으로 산사태 발생가능성을 예측하는 방법 사태물질의 이동경로와 확산범위를 산정함으로써 산사태 위험성을 평가하는 방법 등으로 구분할 수 있다. 우리나라에서 발생된 대부분의 산사태는 여름철의 집중호우에 기인되는 것으로 기반암 상부의 토층에서 발생되며, 강우조건, 지형조건과 지질 및 토질특성 등에 영향을 받는 것으로 알려져 있다. 산사태 조사부터 위험성평가에 이르기까지의 산사태연구는 다양한 산사태를 체계적으로 조사하고 해석함으로써 공학적 관점에서 여러 특징들을 관찰하고 그 특성들을 총괄적으로 해석하여야만 한다. 이 연구에서는 경상남도 마천지역을 대상으로 산사태 현장조사를 수행하였다. 조사결과를 토대로 자연사면 산사태에 대한 최적의 표준모델로 활용할 수 있는 산사태 조사 및 해석 기법을 제안하고자 한다.
