The genesis mechanism and stability analysis of Yangjiagou Landslide in Nanbu Country

Yangjiagou landslide is a small-sale soil landslide in the collapse-landslide deposits,which slides along the contact surface of bedrock and overburden.The landslide movement is in the form of traction.In effect of inducing by heavy rainfall,the front of the landslide deforms and slides.It leads to slow-deformation in the back of landslide for the loose of rear.It poses a great threat to residents at the foot of landslide,passengers and cars passing Ying-pan road.According to deformation and failure characteristics of this landslide,the paper analyzes the genesis mechanism and stability of the landslide.On this basis,the paper proposes a comprehensive prevention measure ofpiles-panels+drainage+tamp-fill crack.
