苏州轨道交通6号线与金鸡湖公路隧道共建方案分析

Joint Construction of Rail Transit Line 6 and the Jinji Lake Highway Tunnel in Suzhou City

苏州轨道交通6号线与金鸡湖公路隧道在跨金鸡湖区段线位基本位于同一位置。为有效节约地下空间资源,避免分期建设造成工程浪费,减小工程风险,减少对金鸡湖的影响,采用将两者同管一体化跨湖建设、高度集约化设计,以取得可观的综合效益。从项目的功能定位、工程特点、建设条件、共建段工法的选择、线路条件、横断面布置、防灾救援模式等方面,对隧道与轨道交通共建段技术方案进行探讨,为类似工程提供参考。

Suzhou rail transit Line 6 and Jinji Lake Highway tunnel are basically located on the same section that crosses under the Jinji Lake. In order to effectively save underground space resource, avoid engineering waste caused by phased constructions, reduce project risks and the impact on Jinji Lake, a co-management integration of the across lake construction and highly intensive design is adopted, looking forward to the comprehensive benefits. In this article, the technical plan of the tunnel section and rail transit joint construction is mainly discussed from aspects of functional positioning, engineering characteristics, construction conditions, method selection of the joint construction section, line conditions, cross-sectional layout, disaster prevention and rescue mode, so as to provide a reference for similar projects.
