Abstract

Abstract

The geological disasters in Yanjin County in Yunnan Province are a big threat to the local people's safety and society development. By analysis on the geology data, combined with field work, we find that landslide occurs in the quaternary loose soil sediments. Collapse occurs in the slope where it consists of sandstone, shale, mudstone, and could be appeared in the high slope in the limestone area, debris flow and other landslide disasters related to earthquake, raining and human engineering activity and mining activity. The main controlling factors are geological structure, topography, slope structure and engineering geology rock group; the main inducing factors are earthquake activity, rainfall, and human engineering activity. Accurate analysis of the geological disasters factors will contribute to the work of disaster prevention and reduction.
