| 摘 要： | 在通用软件ANSYS平台上对静力压桩进行数值分析。提出了位移贯入法，巧妙地利用边界位移条件使桩体贯入，可以考虑弹塑性本构关系、大变形和桩-土滑动摩擦等复杂问题，更符合静力压桩实际情况，具有仿真效果。

| Abstract: | Numerical analysis of static piling based on the commonly used software ANSYS is done. The displacement penetration method is presented, which lets the pile move downward by means of the displacement boundary condition so that to simulate the piling process of jacked pile. The method takes some complex problems into account, such as elastoplastic constitutive law, large deformation and the sliding friction between pile and soil, which is more reality and has the effect of animated simulation. |
