The general finite element software ABAQUS was utilized to analysis and study the steelsheet piles revetment structure.Through a lot of numerical analysis and study,this article researchesthe slope soil plastic deformation and the displacement and internal force of the pile for cantilever steelsheet pile revetment structure in the case of different insertion ratio.The results show that the optimalinsertion ratio of steel sheet pile is 1.05 ～ 1.27.On this basis,this article researches bolt reinforcefor cantilever sheet pile revetment.Adding bolt can improve revetment structure’s deformation andinternal force,constraint slope soil deformation and aim to reducing the pile length.In the case offixed insertion ratio,this article researches anchor’s position and inclination affect on revetment.Through comparing slope soil plastic deformation and structure displacement,it is concluded that theoptimal anchor position is 1.5 ～ 2m from the top of pile,the influence of bolt inclination is small.
