| 摘 要： | 在CFG桩沉降计算公式的基础上,通过选取适当的参数,对某工程实例进行了沉降计算,并进一步对其进行了数字仿真。利用在桩与周围介质之间设置接触面单元来处理桩的刺入变形,得到的模拟值与计算值较为一致。结果证实了该沉降计算公式的可行性。

| Abstract: | Based on settlement calculation formulas of CFG pile,the settlement contact element of some case history is calculated by choosing appropriate parameters,and the numerical simulation is further conducted.Stab deformation of pile is considered by setting contact elements between pile and ambient medium.The simulation result is in agreement with the calculation value,which proves the feasibility of settlement formulas. |
