摘要
利用桩侧摩阻力的发挥与桩的位移成正比的关系求桩在荷载作用下的摩阻力,桩的沉降由桩身压缩变形和桩端沉降之和再乘以半经验公式导出的群桩效应系数yq。该计算方法简单,计算参数的概念明确且易于掌握,可方便地计算桩的沉降是否满足设计要求。
The frictional force of pile under load action is calculated according to the proportional relation between the action of pile-side frictional force and pile displacement. Pile-foundation settlement is obtained by summing compressive deformation of pile stem and settlement of pile tip and multiplying the sum with the effective coefficient yq of pile group from the semi-empirical formula. The calculation procedure is simple, and the concept of calculation parameter is clear and easy to master. By the procedure it is convenient to calculate the settlement and verify the design.
