THE OPTIMUM PRESTRESS OF ANTI-SLIDE PILE WITH ANCHORING CABLE

Based on the design methods and the interaction characteristic of anti-slide pile and soil, a program of contact FEM using contact element is designed. Then, the calculation model is set up; and the bending moment, displacement along the pile with different cable’s prestress and different thrusts are calculated. Finally, the optimum presstress is discussed, which has a significant guide to the landslide control.
