| Abstract: | 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 numerical 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. |
| Keywords: | shallow rocky area building foundation pit subway tunnel optimization analysis |
