| 中文摘要:深基坑在开挖过程中易引起周边地表的变形，因基坑开挖施工周期长且周边环境复杂,对周边地表沉降变形监测及控制则显得至关重要。结合北京市轨道交通指挥中心二期基坑工程地表沉降控制的实践经验,运用ANSYS软件,建立三维数值分析计算模型，并与实测数据进行了对比分析,两者基本吻合。 |

| Abstract:Deep foundation in the excavation process can lead to the deformation of surrounding surface. Because of the long excavation cycle and complex surrounding environment, it is important to monitor and control the deformation of surrounding surface subsidence. In this paper, combining the practice experience of surface subsidence control in the second stage of excavation project of Beijing urban rail transit control center, three-dimensional numerical analysis calculation model was established with ANSYS software. The calculation results tally basically with the measured data. |
