利用有限元软件ANSYS对高桩梁板式码头整体结构进行三维有限元分析。在桩土相互作用的处理中,采用复合地基反力法即p-y曲线法模拟土体,将土体离散成法向与切向非线性土弹簧,分别模拟桩侧土抗力与桩的侧摩阻力及桩端阻力,这较之前常用的按照嵌固点计算的常规算法更能使得进行结构计算时反映出真实情况。通过计算分析,得到基于复合地基反力法的桩基的弯矩与剪力图。比较在同等荷载作用下基于p-y曲线法与常规算法下两种有限元模型的计算结果,通过桩的轴力、弯矩及剪力等计算结果的比较分析得到两种计算方法的差别,为高桩码头的设计计算提供参考。
The Finite Element Analysis of the Whole Structure of the High-beam Beam Wharf Using Finite Element Software ANSYS. In the process of pile-soil interaction, the soil is simulated by the py curve method of composite foundation reaction force, and the soil is dispersed into normal and tangential nonlinear soil springs to simulate the soil resistance of pile side and the side friction of pile respectively And pile-end resistance, which makes it more realistic to carry out structural calculations than the conventional algorithms based on embedding points. Through calculation and analysis, the moment and shear diagram of pile foundation based on the composite foundation reaction force method is obtained. Comparing the calculation results of two kinds of finite element models based on the py curve method and the conventional method under the same load, the difference between the two calculation methods is obtained through the comparative analysis of the calculated results of the axial force, the bending moment and the shear force of the pile, which are high Pile pier design and calculation provide a reference.
