Abstract: Numerical simulation is made for the slope under self-gravity by means of ANSYS software. The slope stress-strain image and displacement vectorgraph of X-Component and Y-Component are analyzed and the general situation of slope failure and the layout of small anti-slide piles are determined for slope disaster prevention. The effect of slope control by small anti-slide piles is analyzed by numerical simulation of the slope controlled by such piles so as to provide assistance to the design and construction of the practical application of small anti-slide piles in controlling slopes.

Key words: Slope, Small anti-slide piles, Landslide, 3D numerical simulation
