水平荷载对单桩竖向承载力影响研究

摘要

基于Mohr-Coulomb强度理论并结合数值模拟分析方法，对不同土体中纯摩擦桩在水平荷载作用下单桩竖向承载力的变化进行了理论分析，结果表明：水平荷载作用下桩基础的竖向承载力会有所下降。%Based on Mohr-Coulomb strength theory and combined with the finite element software ABAQUS,the change of the vertical ultimate bearing capacity of pile is analyzed theoretically,aiming at the pure friction pile in different soil under different levels of horizontal load. The re-sults show that vertical bearing capacity of single pile will fall under the horizontal load.
