Abstract Indoor experiments were carried out on models with geometric similarity of 1∶20 to study h-shaped anti-sliding piles mechanism. The load was applied in steps by a jack，and the moment and deformation patterns of three h-shaped anti-sliding piles with different row spacings and different beam positions were obtained. The pile-soil interaction model of h-shaped anti-sliding pile was established by finite element software ABAQUS；and several design parameters of pile were analyzed and optimized. The results show that the optimal pile row spacing is 5 times pile diameter；the optimal stiffness of connecting beam is 1.5 times of pile；the optimal embedded depth of pile is 3/8 of the length of front row pile. Finally，the conclusions were successfully applied to treatment of an actual landslide in Nanning.
