To improve the defects of anti-sliding pile calculation

the transfer matrix algorithm is applied to the internal forces calculation for anti-slide pile structure. Point matrix and field matrix are derived. Utilizing them could complete the internal forces calculation for common anti-slide piles

anti-slide piles with concentrated loads on the pile top

and the anti-slide pile under concentrated forces on pile body. According to the working principle of the anti-slide pile with anchor cable

transfer matrix calculation formulas of different stress stages are given. The corresponding calculation program is made based on MATLAB. It could get the internal forces and displacements of any section of the pile body quickly and easily and calculate the foundation reaction. Finally

the calculation analysis for the internal forces and displacements of different stress stages of the anti-slide pile with anchor cables is made through a specific calculation example. The results show that there will be larger shear and bending moments

smaller displacements at the loaded segment under the action of anchor cable prestress. In the stage of displacements coordination

the shear at the sliding surface and the anchorage segment increase significantly

bigger bending moments appear at the anchorage segment

and forward displacements appeared at the pile top.
