| 摘 要： | 采用平面应变有限元方法，对土体运动作用下的被动桩桩土相互作用进行分析。分析中考虑土的塑性和大应变，并在桩土间设置接触单元，重点研究桩周土的位移模式和土体处于不同状态时接触应力的分布规律，讨论了群桩中桩与桩间的相互作用对接触应力的影响。

| Abstract: | The pile-soil interaction behavior of passive pile under soft soil movement action was analyzed using plain strain finite element analysis including the plasticity and large strain of soil. The contact elements were defined to represent the contact behavior between the pile and soil. The focus of study was on the model of the soil movement around the pile and the contact stress distribution at the pile-soil interface in the different states of soil. The effects of pile-pile interaction of pile groups on the contact stress were discussed. |
