FLAC3D在分析单桩竖向荷载作用下桩—土相互作用规律中的数值模拟研究

FLAC3D是以拉格拉日差分法为基础的一种数值模拟,近几年已广泛的应用于工程领域,本文旨在用FLAC3D对桩土材料模拟进行简单的介绍,结合单桩在竖向荷载作用下桩对“昔格达”回填土的影响,利用FLAC3D来模拟单桩竖向荷载下桩土作用的变化规律,数值模拟结果表明FLAC3D对单桩竖向荷载下的桩侧摩阻力、桩体轴力和中心点的分布规律进行模拟时效果良好。

Analysis of single pile under vertical load of pile - soil interaction in the numerical simulation using FLAC3D

FLAC3D is a numerical simulation method which based on Lagrangian Analysis of Continua, in recent years has been widely used in engineering fields, The sofeware FLAC3D is briefly introduced and the different techniques for the simulation of pile-soil materials, combined with the role of single pile in the vertical load under the pile of "Xigeda" back fill, application of FLAC3D to simulate the single pile under vertical load variation of pile-soil effect, numerical simulation results show that the FLAC3D can easily load on single pile under vertical pile shaft resistance, pile axial force and the center of the distribution of simulated.
