A formulation for passive type cotter pile against the landslide with multiple slip surfaces has been proposed in this paper. The prime focus was the coupling of two different approaches. One is Chang's pile equation, which was extended to deal with displacement discontinuity at slip surface and the other is the slope stability assessment theory similar to Janbu's. By using the proposed formulation, an engineer can obtain almost all the state parameters with regard to both the pile and landslide mass, necessary to design the pile for landslide prevention. Example calculations show the significant differences between one layer of landslide mass and two or more layers with state quantities, such as stress, displacement etc.
