Abstract:: According to landslide deformation rule and strength reduction method, a finite element feature point analysis method is built. Using this method to study vegetable oil plant landslide deformation and damage process, the conclusions are reached as follow: Vegetable oil plant landslide belonging to Traction landslide, in the initial stage of bedding slipping; the front part of landslide deformation relatively large; the landslide reached the limits of balance.From the curve of ΔX/ΔFsr by strength reduction method, there is a significant deformation accelerated process, the safety factor of the overall landslide is F=1.15, the safety factor of dangerous rear local landslide is Fr=1.20.
