| 摘 要： | 为解决传统桩基承载力低的问题,基于差异沉降控制优化设计桩基。分析桩基设计存在的问题,主要包括:桩基支承刚度设定误差高、桩基差异沉降大、桩基结构设计不合理,通过设定桩基支承刚度,控制桩基差异沉降,采用桩基塌孔承桩断裂结构,实现对桩基的优化设计。设计实例分析,结果表明,设计的桩基承载力明显高于对照组,能够解决传统桩基承载力低的问题。

| Abstract: | In order to solve the problem of low bearing capacity of traditional pile foundation,based on the optimization design of pile foundation based on differential settlement control,this paper analyzes the problems existing in the design of pile foundation,mainly including high setting error of pile foundation supporting stiffness,large differential settlement of pile foundation,and unreasonable design of pile foundation structure.By setting the supporting stiffness of the pile foundation,controlling the differential settlement of the pile foundation,and adopting the collapsed structure of the pile foundation,the optimal design of the pile foundation is realized.The results show that the designed bearing capacity of pile foundation is significantly higher than that of the control group,which can solve the problem of low bearing capacity of traditional pile foundation. |
