Abstract: By the example of the specific landslope,this paper gives the sliding mechanics of the landslope on the base of the detailed geologic conditions analysis, and presents the stability of different region according to the evaluating of all regions. At the same time, we use the limit equilibrium method to evaluate the local stability and the whole stability of the landslope, then give the design parameters. According to these, such measures as mesh shot concrete, concrete facing and anchor are applied to reinforce the landslope.
