摘要
福州三环路金鸡山隧道和罗汉山隧道的辅路隧道与主路隧道并列形成了全国罕见的"小净距+连拱+小净距"群体隧道,且辅路隧道晚于主路隧道进洞施工。介绍了项目概况,分析了对多孔群体隧道进行建模并对各施工步序进行模拟计算的有关结果,论述了后建辅路隧道对已建主路隧道造成的不利影响,阐明了加强后建辅路隧道支护措施的必要性。
The main road tunnel and relief road tunnel of Jinjishan Tunnel and Luohanshan Tunnel on the Third Ring Road in Fuzhou are located side by side and present the nationwide rare group tunnels consisting of the neighborhood tunnel, multi-arch tunnel and neighborhood one, and the relief road tunnel was constructed after the main road tunnel. This article introduces the general situation of the project, analyzes the model building for the porous group tunnels and the relational computed results with the simulation for their each construction step, discusses the adverse effect that the completed main road tunnel was impacted by the relief road tunnel constructed after, clarifies the necessity of strengthening the supporting measures applied to the relief road tunnel constructed after.
