| 摘 要： | 本文从实验入手分析了软粘土中静压桩贯入时 ,引起的土体位移场变化规律 ,通过对一些因素加以控制 ,观测了单桩和有邻桩存在时 ,土体的侧移和隆起规律。然后通过二维弹塑性有限无模拟桩的压入过程 ,通过在桩侧设置接触面单元 ,获得了挤土过程中 ,土体的位移和土中的应力分布。并通过比较两个结果 ,得到了合理的结论。

| Abstract: | The rule of change of soil displacement field during the penetration of silent piling in soft clay is analysed through experimental ways. With some factors under controlled, the lateral displacement and heave of a single pile and piles are observed .The penetration of pile is simulated by two-dimension elastic FEM.Through the contacting elments on pile surface, the stress distribution in soil and displacement of soil mass are observed. Comparision of two tests results, a reasonable conclusion is obtained. |
