| 摘 要： | 根据有效应力原理和比奥固结理论，应用弹塑性有限元研究基坑开挖降水过程中的地面沉降、支护结构侧向位移等变形，并以实际工程为例分析不同止水帷幕深度对基坑变形的影响，结果证明，为有效控制地面沉降和支护结构侧向位移，确定合理的止水帷幕深度非常重要。 |
| 关 键 词： | 基坑 降水 地面沉降 |

| Abstract: | On the base of effective stress principle and Biot's consolidation theory,the ground settlement near the foundation pit and the displacement of retaining structure in the process of excavation and dewatering are studied by elastic-plastic finite element method;and the influence of depth of water cut-off on deformations is analyzed with an engineering case.The results show that a reasonable depth of water cut-off is very important to the effective control of the ground settlement and lateral displacement of retaining structure. |
| Keywords: | foundation pit dewatering ground settlement |
