有限元分析复合地基的水平受力机理

Finite element analysis on horizontal force mechanism of composite foundation

利用ANSYS8.0对复合地基进行了有限元仿真分析,分析了单桩复合地基在水平荷载作用下的变形性状,主要讨论了竖向载荷大小和垫层厚度不同对桩顶水平位移的影响,研究结果表明:竖向载荷越大,垫层厚度相对较大,都会减小桩顶位移,有利于桩身安全。

The following paper carries out finite dement simulation analysis on composite foundation by ANSYS8. 0, analyzes the deformation behavior of single-pile composite foundation under the action of horizontal load, discusses the influences of the size of vertical load and thickness of cushion on horizontal displacement of pile top, and shows by researching results that big vertical load and thick cushion course can reduce the displacement of pile top, which is propitious for the safety of pile.
