在地铁车站施工中,新建线路穿越既有线路车站是不可避免的问题。为保障施工影响范围内地下建筑物的安全,以及围岩与结构的稳定,针对具体工程,对需要采取措施的近接施工,采用力学仿真分析,总结出合理的设计施工方案。
In the subway station construction, the new line crossing the existing line station is an inevitable problem. In order to ensure the safety of underground buildings and the stability of surrounding rock and structure within the construction influence scope, according to the specific project, the mechanical simulation analysis is adopted for the proximity construction requiring measures to be taken, and a reasonable design and construction plan is concluded.
