摘要

随着地下空间的开发利用，地铁隧道周边的地下工程项目日益增多，地下工程建设对隧道的影响日益明显。以杭州地铁1号线周边基坑工程为例，利用现场实测结果，分析了基坑开挖前和开挖过程中水平位移和竖向位移的变化规律。研究发现，围护结构施工过程中的扰动对隧道变形有显著影响。

Comparative analysis on the influence of foundation pit excavation and enclosure construction on subway deformation

As the development and utilization of underground space, underground engineering projects adjacent to the subway tunnel increase daily, and the effects of underground engineering construction on the tunnel become noticeable. Based on the foundation pit project neighboring Hangzhou metro line 1, in situ measurement results are used to analyze the horizontal and vertical displacement, alone with horizontal convergence, before and during the excavation. It’s found that the disturbance during the construction of the enclosure structure has a significant effect on the tunnel deformation.
