"Pin"type anti-slide pile prevention programs is used to treat Suoertou landslide

for the evaluation of the effect of its governance

by means of the numerical simulation software FLAC

3D

to compare the stress

displacement of landslide and trends when taking the"Pin"type of anti slide piles and no piles.As a result that after the anti slide pile supporting measures

the landslide displacement decreases

and the slopeis stable.The governance effect is marked.The slope stress is concentrated on 10 mplatform and local collapse may occur under the unfavorable load

in order to increase the safety margin

we suggested a retaining wall.The retaining side pile has uniform stress.The front row pile displacement is significantly less than the

back row pile in"Pin"type of anti slide

so in order to make the anti stress more reasonable

it is appropriate to increase the row pile spacing or reduce the front pile cross section during the design.
