地铁一号线徐家汇站穿越施工影响的数值分析

Numerical Analysis of Crossing Construction Effect in Xujiahui Station of No.1 Subway

以上海轨道交通九号线徐家汇站工程的实际施工为背景,对徐家汇站中央换乘大厅改建施工、轨道交通九号线对一号线徐家汇站穿越段施工进行三维有限元分析,模拟了施工过程对地铁一号线的影响。得出了一些规律性的认识和有价值的结论,给施工提出了一些有益的建议。

Taking the practical construction in Xujiahui station project of No. 9 Shanghai track traffic as a background, the 3D FEM analysis of the rebuilding construction in Central Change Concourse of Xujiahui station and the construction of crossing section from No. 9 track traffic to Xujiahui station of No. 1 subway is carried out; the influence of construction process on No. 1 subway is simulated. Some law knowledges and conclusions of value are obtained, and some profitable suggestions are put forward for construction.
