| 摘 要： | 考虑群桩效应,分析了导管架平台在水平载荷作用下桩土间相互作用的计算原理。在AN-SYS软件中结合p-y曲线法,对某导管架平台分别建立了考虑和不考虑群桩效应的非线性有限元模型,以及泥面下6倍桩径处加固支的简化模型。通过对比3者的计算结果,得出群桩效应影响导管架平台结构计算的有关结论。

| Abstract: | Considering the pile group effect,the calculation principle of pile-soil interaction was an-alyzes when the Jacket platform was under lateral loads. Using the p-y curve method,nonlinear fi-nite element models of jacket platform considering was built and not considering the pile group effect,a simplified model with unmoved hinged supported in 6 times the pile diameter under the mud in the ANSYS software. By comparing the results of the three, some conclusions were drawn for the influence of pile group effect on the structure calculation of jacket platform. |
