According to the limit lateral force acting on the stabilizing pile suggested by SHEN Zhu jiang, a simplified method to analyze the pile slope stability is presented. The admissible bending moment of the pile and the pile length below the slip surface are considered in the method. It is indicated that the calculated results using the method proposed in this paper are more reasonable than those obtained by the method recommended in the Chinese Foundation Code of Harbour Engineering. It is proposed that the analytical method for the pile born horizontal load be used to analyze the pile supported pier behaviour. The admissible bending moment of the pile, the pile length below the slip surface, the factor of safety of pile slope and the constrained condition of the pile top are considered in this method. The displacement, rotation, bending moment, shear force of the pile may be calculated using this method.
