A modified method is proposed in this paper to evaluate the ultimate lateral soil resistance of rigid piles in cohesionless soil on slopes, which is based on wedge-equilibrium analysis. The method assumes that the soil resistance in front of the pile is compressed under the lateral load and that a wedge is formed without damage. The frontal soil resistance and side shear resistance are mainly considered and the response of the lateral resistance rigid pile in the cohesionless soil slope is described by hyperbola p-y curves. To validate the modified theoretical solution, the model is compared with the test results of the field pile and numerical simulation results. Combined with numerical simulation, the effect of slope angles on the lateral resistance around the pile is discussed. The results show that the modified theoretical solution is feasible for rigid piles in cohesionless soil on slopes.

提出了一种改进的方法，基于楔平衡分析，评估了无粘性土在斜坡上的刚性桩的极限侧向土的抗力。该方法假设桩的前方的土抗性在侧向荷载作用下受到压缩，并且形成了楔形而没有损坏。主要考虑了正面的土阻力和侧面的抗剪力，用双曲线p - y描述了无粘性土边坡中的侧向阻力刚性桩的响应。曲线。为了验证改进的理论解，将模型与现场桩的测试结果和数值模拟结果进行比较。结合数值模拟，讨论了倾斜角度对桩身侧向阻力的影响。结果表明，改进的理论解对边坡无粘性土中的刚性桩是可行的。
