Abstract There are three failure modes of landslides，that is，retrogressive landslide，thrust-type landslide and complex landslide. Different failure modes need different reinforcement measures. According to the definition of the point safety factor，the point safety factor along the slip surface can be calculated. The failure mode can be quantitatively described based on the distribution of the safety factor along the slip surface and the suitable reinforcement measures can thus be suggested. The calculated results of three classical landslides show that the failure characteristics can be well explained by the point safety factor along the slip surface. Finally，this method is applied in a large deposit located in the west of China. The engineering geological structure and the failure mechanism of the multi-layer deposit and the stability of the slope were preliminary analyzed based on the field survey and the effective reinforcements were suggested.

Key words： slope engineering multi-layer deposit failure model retrogressive landslide thrust-type landslide Fuliyuan landslide
