基坑工程施工过程中地铁保护措施的有效性分析

Effectiveness Analysis of Subway Protection Measures in Foundation Pit Construction

随着建设用地的日趋紧张,地下工程交叉建设的情况越来越多,地下工程施工的相互影响不可避免,其中又以基坑工程施工对既有地铁结构的影响最受关注。因此在进行基坑工程设计和施工时就要采取地铁结构保护措施控制既有地铁隧道的变形,确保其安全。文章从基坑工程施工对地铁结构的影响入手,探讨了基坑工程施工过程中的地铁保护措施,并通过实际监测验证了保护措施的有效性。

With the increasing tension of construction land,there are more and more cross constructions of underground projects.The interaction of underground project construction is inevitable,among which the influence of foundation pit construction on existing subway tunnels is the most concerned.Therefore,how to take effective protective measures to control the deformation of existing subway tunnels and ensure their safety has become the key to the construction control of adjacent foundation pits.
