Stability and forming mechanism of the Zhongxi landslide in Ningguo City

The Zhongxi Slide in Ningguo City is a large-scale slide caused by cutting sidehill. The paper expounds the environmental geological conditions of the Zhongxi Slide, discusses the geological characteristics, the structure of rock mass, the forming conditions of the Zhongxi Slide and the factors which may have influence on the slide stability as emphasis. The engineering properties and slope stability are tested,analyzed and computed. Based on these discussions, a feasible comprehensive treatment scheme is put forward at last.
