柔性桩的三维弹塑性有限元研究

Elastic-plastic Research on Flexible Pile by 3D-FEM

选用刻画土与柔性桩塑性特点的弹塑性本构模型 ,利用三维有限元对土与柔性桩在荷载作用下的塑性区扩展状况进行了研究 .计算结果表明 ,柔性桩对具有不同力学特性的土层 。

The elastic-plastic constitution has been employed in order to consider the plasticity of soil and flexible pile. The research has been made for plastic development of the soil and flexible pile under different loads. The calculated results show that flexible pile features different load transmission with the variation of mechanical characters of soil layers.
