动荷载条件下波浪桩力学性能分析

Analysis of mechanical properties of wave pile under dynamic load

本文以广东省台山市新昌水波浪桩工程为例,采用有限元分析软件分析了波浪荷载和地震荷载作用下,波浪桩的动力响应规律。研究成果表明,波浪荷载作用下,桩基的位移呈非线性变化趋势明显,位移先增大后减小。此外,在地震荷载作用下,波浪桩头的加速度和位移都随着动载荷的增加而增加,振幅响应较大,能够响应0.5 g至2.5 g的加速度,研究成果可为相关工程提供参考。

Taking Xinchang water wave pile project in Taishan City,Guangdong Province as an example,the finite element analysis software is used to analyze the dynamic response law of wave pile under wave load and seismic load.The research results show that under the action of wave load,the displacement of pile foundation shows an obvious nonlinear change trend,and the displacement first increases and then decreases.In addition,under the action of seismic load,the acceleration and displacement of wave pile head increase with the increase of dynamic load,and the amplitude response is large,which can respond to an acceleration of 0.5 g to2.5 g.The research results can provide reference for related projects.
