摘　　要：提出的桩 -岸坡稳定简化计算方法 ,考虑了桩的允许抗弯弯矩和桩在岸坡和滑动面下的嵌固深度 .算例表明 ,简化计算法的结果比港工规范中推荐的方法合理 .在此基础上 ,建议采用计算水平承载桩的方法来计算桩基性状 ,考虑了桩的允许抗弯弯矩、滑动面下的嵌固深度、岸坡稳定安全系数和桩头联结条件等多种情况 ,可得出桩基的挠度、转角、弯矩和剪力 .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.
