| 摘 要： | 采用数值模拟手段,对海上风电基础结构大直径钢管桩水平静载荷试验进行仿真,其中,仿真试验数值模型中桩土之间设置接触单元对桩土相互作用特性进行模拟。对仿真试验结果的处理与分析表明:桩土之间接触单元的设置更为真实地描述了桩土接触的性状;计算得到的p～y曲线较与一些已有方法的结果相比存在差异。

| Abstract: | Numerical simulation was employed to study the horizontal load tests on large-diameter steel piles for offshore wind turbines.In the model,the pile-soil interaction was simulated by using the contact interface elements between the piles and the soils.The simulated data are processed and analyzed.The results reveal that it is reasonable to set the contact interface elements between the piles and the soils.The p-y curves obtained by the numerical simulation are not in good agreement with those by the existing... |
