基于有限元法的柔性靠船桩设计分析

选取广州港某扩建码头中使用的柔性靠船桩作为工程实例,采用P-Y曲线法,利用通用有限元软件ANSYS对柔性靠船桩进行受力分析;同时土体采用Mohr-Coulomb模型,利用有限差分软件FLAC建立实体土单元与柔性靠船桩相互作用模型进行桩的受力复核,并将二者的计算结果进行对比分析,得出较为合理的设计成果,为港工设计人员提供有效参考。

Analysis and study on flexible dolphin design based on finite element method

Taking the flexible dolphin of a jetty extension project in Guangzhou port as an example,applying P-Y curve method in the pile-soil interaction model,we analyzed the internal force of the flexible dolphin by general finite element software ANSYS.Meanwhile,using Mohr-Coulomb constitutive model for the soil and adopting the finite-difference software FLAC,we established the pile-soil interaction model to check the internal force of the flexible dolphin.According to the comparison between the two results,a reasonable design conclusion is obtained,which will contribute to obtaining a valuable reference for the harbor engineering designers.
