| Abstract: | Based on the design methods and the interaction characteristics of anti-slide pile and soil,a program of improved FEM with contact element is developed.A calculation model is set up to calculate the bending moment and displacements along the pile with different cable's prestresses and different thrusts.The optimum presstress is discussed,which is important for the landslide control. |

| Keywords: | problem of pile-soil contact anti-slide pile cable with prestress optimum prestress |
