摘　　要：南京市和燕路-八卦洲过江隧道为盾构形式隧道,共设两孔,为了解决八卦洲现状供水问题,集约化利用过江隧道下部空间,在每孔隧道检修舱下部设置管沟敷设一根DN500供水管线,连通八卦洲供水管网和江南城北水厂供水管网,实现八卦洲由江南供水的格局。对管线最大泄水量、管材的优化比选、附属设施的设置、监测和监控系统、水锤模拟及防控措施等进行了研究,论证了在隧道内敷设供水管线的可行性,通过采取一系列的措施,可以确保供水管线和隧道同步运行的安全性,减小了供水管线与隧道的相互影响,为今后同类型项目提供了参考。Heyan Road-Baguazhou river crossing tunnel in Nanjing is a shield tunnel with two holes.In order to solve the current water supply problem of Baguazhou and effectively utilize the lower space of the tunnel,a DN500 water supply pipeline was set up under each tunnel inspection cabin to connect the water supply network of Baguazhou and the water supply network of Jiangnan Chengbei waterworks,so as to realize water supply of Baguazhou from Jiangnan.The maximum discharge of the pipeline,optimal selection of pipes,setting of ancillary facilities,monitoring and control system and simulation of water hammer and prevention and control measures were explored,and feasibility of laying water supply pipeline in the tunnel was demonstrated.A series of measures were taken to ensure the safety of the synchronous operation of the water supply pipeline and the tunnel,and reduce the interaction between them,which provide a reference for similar projects in future.
