Conditions of application analysis of per-stressed anchor-wire anti-slide pile by FEM

Prestressed anchor friction pile as the mainstream measure of control landslide,to change the ordinary anti-slide pile unreasonable cantilever stress state,which greatly reduces the bending moment of pile cross-section and buried depth.The last 20 years been widely applied.For the different conditions of landslide,select the most suitable prestressed anchorage cable anti-slide pile structure,is problem worthy of study.Against ordinary anti-slide pile,distribution of single anchor cable anti-slide pile and multi-anchor cable stabilizing piles,article using the finite element method analysis the distribution of internal force of the different thrust the case,carried out a mechanical comparison,come to the conditions of application of a different structural forms of the anti-slide pile,available anti-slide pile design reference.
