软土地区地下通道上跨运营地铁区间的保护措施研究

Study on Protection Measures for Underground Tunnel Overpassing Metro Area under Operation in Soft Soil Area

近年来,地铁相关部门对于地铁保护区范围内的工程建设影响的控制要求日益严格。软土地区城市地下通道上跨运营地铁区间隧道保护措施复杂。从控制地下通道施工卸载的角度出发,对上海虹桥迎宾一路地下通道斜交上跨地铁10号线区间的保护措施进行研究分析,为类似上跨地铁区间的地下工程设计、施工提供有益参考。

In recent years, the relative departments of metro increasingly strictly control the engineering construction influence in the range of metro protection area. The protection measures for the urban underground tunnel to cross over the metro area under operation in the soft soil area are complicated. The article studies and analyzes the protection measures for the underground tunnel obliquely crossing over the area of Metro Line 10 in Hongqiao Yingbin Road I of Shanghai from the angle of controlling construction unloading of underground tunnel, which provide the beneficial reference for the design and construction of the similar projects crossing over the metro area.
