根据Tomio基于塑性变形理论法提出的因土体移动产生的作用于桩的侧向力计算公式计算桩在滑面以上部分受到的作用力 ,对单跨梁码头桩基结构及单排桩结构与土体的相互作用进行了分析 ;并对在一软土地基上建造的桩基码头进行了受力分析 ,计算桩的侧向力时滑面位置根据土体变形资料和地质资料确定。计算结果表明 ,当考虑横梁对桩的约束作用时 ,计算结果与实测资料吻合得很好 ,说明提出的分析方法是可行的 According to Tomio plastic deformation theory proposed by the soil movement of the pile acting on the lateral force formula to calculate the pile in the sliding surface above the part of the force received on the single-beam piers pile structure and single-row pile structure and The interaction between the soil and the soil is analyzed, and the force analysis of the pile foundation pier constructed on a soft soil foundation is performed. When calculating the lateral force of the pile, the sliding surface position is determined according to the deformation data and geological data of the soil. The calculation results show that the calculated results are in good agreement with the measured data when considering the restraint of the beam on the pile, which shows that the proposed method is feasible
