There are few mature models or methods for structural calculation of h-type pile currently.This paper introduces a new method to calculate the structure of h-type anti-slide pile based on finite different method（FEM）.The h-type pile was divided into two different parts to establish difference equation in light of the location of potential slip surface.The Finite difference equations set for h-type anti-slide pile was deduced and calculated based on boundary condition.The structural model tests were carried out to check the effectiveness of the calculation method based on FEM.Research shows that the values of displacement and stress calculated by FEM at same position are in agreement well with that from structural model test

which shows that the method of FEM in solving paramters of anti-sliding pile

such as displacement and stress

is accrate and reliable.At the sametime

the h-type anti-slide pile overcomes the problem of stress concentration compared with traditional anti-slide pile

because the alternating stress of front row pile and back pile of h-type pile can reduce maximum stress of pile effectively

Finally the displacements at the same height of front row pile and back row pile of h-type pile are almost same

which shows that h-type pile has an outstanding ability of work in coordination.
