综合管廊穿越地下交通隧道的共建设计

Co-Construction Design of Utility Tunnel Crossing Underground Traffic Tunnel

以某综合管廊穿越地下交通隧道为例,分析讨论了两者的竖向关系及协同设计。综合管廊采用“管廊变舱+结构共建”的形式上跨交通隧道,通过调整管廊的舱室数量、净高、净宽,将管廊内敷设管线的重新排布,尽可能减少了管廊穿越对交通隧道竖向设计的影响,起到集约利用城市地下空间资源,减少工程投资的作用。

Taking a utility tunnel crossing an underground traffic tunnel as an example,the vertical relationship and collaborative design of the both are analyzed.Combined with the utility tunnel crossing the traffic tunnel by the form of"cabin change of utility tunnel+structure co-construction",by adjusting the cabin quantity,clear height and clear width of utility tunnel,the pipelines are rearranged in the utility tunnel in order to reduce the influence of utility tunnel crossing on the vertical design of traffic tunnel as far as possible,which plays the role of the intensive utilization of urban underground space resources and reduction of engineering investment.
