通用有限元模拟抗滑桩或桩板墙计算

General Finite Element Calculation of Anti-Slide Pile or Pile Wall

摘要: 随着经济的发展和景观、造型对结构工程有越来越高的要求，通过常规软件对异型结构进行计算会存在较多限制，主要受软件的模块或者模型限制，无法对变截面或异形结构进行计算。本文通过研究模拟，介绍通用有限元模拟岩体水平约束、梁单元模拟抗滑桩(或桩板墙)，并通过spa2000及midas Civil软件模拟计算与理正岩土进行对比，验证本文提出的岩土体节点刚度计算方法的正确性和可靠性。

Abstract: With the development of economy and the increasing demand of landscape and modeling for structural engineering, there are many restrictions on the calculation of special-shaped structure through conventional software, which is mainly limited by the software modules or models, so it is impossible to calculate the variable cross-section or special-shaped structure. In this paper, through research and simulation, the general finite element simulation of rock horizontal con-straint and beam element simulation of anti slide pile (or pile sheet wall) are introduced, in this paper are verified by comparison between the simulation calculation of spa2000 and midas Civil software and Li-zheng geotechnical software. Verify the correctness and reliability of the stiffness calculation method of rock soil joints proposed in this paper.
