地铁与地下综合管廊统筹协调问题探讨

Discussion on Coordination between Metro and Utility Tunnel

以郑州市轨道交通8号线工程为例,全面梳理地铁与综合管廊的空间关系,并按建设时序进行分类,深入研究各种条件下处理地铁与管廊工程的协调方案,从地铁区间、车站附属以及车站主体3个方面提出综合利用城市地下空间可实施的解决方案。综合管廊与地铁区间相交时,地铁设计在纵向上加大埋深;与车站附属相交时,根据建设时序选择双方上下层关系;与车站主体相交时,根据建设时序选择合建或者绕避,可为类似工程提供借鉴思路。

Taking Zhengzhou Metro Line 8 as an example, the paper summarized the spatial relationship between the metro and the utility tunnel, classified the construction sequence of them and researched the coordination scheme of subway and utility tun- nel under various conditions. The solutions to the comprehensive utilization of urban underground space are put forward from three aspects： metro tunnels, station subsidiary and station main body. When the utility tunnel intersects the metro tunnels, the design of the metro tunnels should increase the depth in the longitudinal direction; when the utility crosses the station auxiliary, the relation between the upper and lower layers is selected according to the construction timing; when crossing with the main body of the station, the co-building or bypassing shall be selected according to the construction timing.
