基于Ansys的人工基床钢套管波流力作用下稳定性分析

Stability Analysis of the Steel Pile in Artifucial Bed by the Action of Wave-Current Force Based on Ansys

基于宝钢马迹山港矿石中转码头工程,采用Ansys数值模型,将桩土作用力简化为弹簧模型,水平侧向荷载作用通过P-y曲线将土体性质赋予COMBIN39单元,轴向荷载作用通过t-z曲线将摩擦阻力赋予COMBIN39单元,从而对不同水位、不同桩径、不同基床厚度、不同波高条件下的钢套管所受水平总力和管端位移值进行计算。通过对所得力和位移特性的对比分析得出相应特定结构人工基床的理论厚度范围,为以后的设计施工进行了有益探索。

Based on the ore transit wharf in Majishan Baogang,through the Ansys Numerical model the pile-soil interaction is simplified into a spring model,the horizontal lateral loads confer soil properties to COMBIN39 unit by P-y curve axial loads confer friction to COMBIN39 unit by t-z curve calculate the total horizontal force and displacement of the pile end under different water levels,pile diameters,foundation bed depths and wave heights.Through comparing force and displacement characteristics,the rang of the artificial bed thickness is given.It can provide beneficial exploration and reference for the following design and construction.
