为确保广州浅岩区紧邻地铁隧道某建筑基坑的顺利实施,同时保障地铁安全运营,对基坑支护结构形式进行了探讨,并采用平面和三维数值手段分析了基坑开挖过程中采用附加支撑后对地铁隧道的影响。分析结果表明,采用附加支撑后,双排桩支护结构结合中心岛法开挖可有效控制支护结构和地铁隧道的位移,并减少工程成本。

To ensure the smooth implementation of a building excavation adjacent to the subway tunnel in Guangzhou shallow rocky area, while safeguarding the subway safe operation. The foundation pit supporting structure type are discussed, and the plane and three-dimensional numeri- cal method analyze are used to analysis the influence of pit excavation on the subway tunnel after setting up additional support. The analysis showed that, with additional support, the double rows pile retaining structure with center island method can effectively control the displacement of the supporting structure and subway tunnels, and reduce the cost of the project.
