Abstract A new type of rock landslide failure mode in red bed area，lateral drag landslide，is proposed after detailed field investigation and mechanics analysis of Fengyan village landslide in Yilong County，Nanchong City，Sichuan Province. During the movement of the main sliding body of the landslide in the heavy rain，the dragging force will be generated along the sliding direction of the contact zone of the boundary on both sides，which will lead to the dragging deformation of the slope on both sides. The longitudinal length of landslide is smaller than the transverse width and the surface lateral deformation shows obvious strong and weak zones. Firstly，the slope structure conditions，lithologic composition conditions，free face conditions and external triggering conditions which must be had for the occurrence of the drag landslide are systematically studied and identified. Then on the basis of the comprehensive force analysis of landslide，the three-dimensional stability evaluation model and criterion of main sliding body and dragging body are established. Finally，in order to prevent the subsequent deformation and failure mode of the drag landslide，the paper puts forward some suggestions on surface drainage and groundwater dredging，supplemented by appropriate retaining engineering. The research findings have certain guiding significance for the prevention and control of red bed landslide.

Key words： slope engineering drag landslide formation mechanism three-dimensional stability evaluation prevention measures
