城市综合管廊与轨道交通共建设计探讨

Discussion on Design of Urban Utility Tunnel and Rail Transit Common Construction

城市轨道交通和综合管廊均属于城市地下空间开发利用,分别解决"人通行"和"物占位"的空间问题,为避免道路反复开挖,降低成本,将两者结合同步规划建设,有效开发地下空间是一个新的探索方向,目前国内相关研究成果不多。从综合管廊在轨道交通车站主体、附属以及区间等三处节点着手,通过两者结构及形式的相互改变,探讨了两者在竖向高程及空间位置关系,提出了几种典型的共建方案,可为类似工程设计提供参考。

Urban rail transit and utility tunnel all belong to urban underground space development and utilization project, which could solve the ＂pass＂ and ＂content place holder＂ space problems. In order to avoid repeated excavation road and to reduce costs, a combination of the two projects was deter- mined via synchronized planning and construction. The effective development of underground space is a new exploration field. At present, the domestic relative research achievements did not obtained. In this paper, from three nodes, such as the utility tunnel in the main body of the rail transit station, the subsid- iary and the interval space, etc., the relationship between the vertical height and space between the two position, was discussed by both the structure and form of change each other. Then, a variety of flexible build plans were put forward, which can provide a reference for similar project design.
