초록 An investigation on geologic hazard was carried out in the study area, which includes the topographic maps of Kumsan, Iwon, Youngdong, Kwanki and Boun, all at a scale of 1:50,000 and encompasses approximately 3,060㎢, to provide information on many aspects of slope stability. In the Boun area, about 160 landslides occurred due to the heavy rainfall on August 12, 1998, not only killing lives but also damaging properties. According to the available information, it was found out that the most common type of landslides in the study area was debris flow induced by heavy rainfall during the rainy season. It was also found out that the flows mostly occurred in the slopes having an angle between 30。-45。. Based on the results of physical and direct shear tests on disturbed and undisturbed samples, the soils occurring in the landslide areas were generally classified as SP-SM and SM. The shear strength was determined at 0-5 kPa(Cohesion) and 22。-35。(internal friction angle)
