| 摘 要： | 为了研究深开挖过程中渗流场与应力场的变化规律及其导致的基坑稳定问题，基于比奥固结理论，并将其扩展应用于弹塑性分析领域，将渗流场水力作用与应力场淹合，并通过有限单元法模型，力求得到深基坑开挖及降水过程中，开挖范围及邻近区域地面沉降等环境效应的基本规律的认识，为深基坑开挖设计与信息化施工提供借鉴。

| Abstract: | In order to research the variation law of seepage field and stress field during excavation and its influence on the problems of stability of deep foundation pit,on the basis of Biot＇s consolidation theory which was extended to elastic-plastic scope we coupled the hydraulic action of the seepage field with the stress field through finite element simulation,we tried to grasp the basic laws of environmental effects,such as ground surbsidence in the range of excavition and adjacent zones in the process of excavation and rainfall so that we could offer examples for the excavation design of deep foundation pit and imformalized construction. |
