摘要
结合中国几例典型沉管法隧道工程,详细介绍中国沉管法隧道在基槽开挖与航道疏浚、干坞建设、管节预制、管节浮运、管节系泊、管节沉放、接头处理和基础处理等关键技术的应用现状。以在内河中游径流河道中修建的南昌红谷隧道和在外海修建的港珠澳大桥岛隧工程海底隧道为例,对在江河和海洋中修建沉管隧道的关键技术创新进行总结,包括:南昌红谷隧道管节浮运与沉放、管节沉放基础差异沉降控制、水下立交接线实现过江通道与沿线路网全互通快速衔接、水下空间开发与修建避难疏散大厅等关键修建技术创新,港珠澳大桥岛隧工程沉管法隧道干坞建设、管节预制、管节沉放和基础处理等关键修建技术创新。结合目前中国修建沉管法隧道涌现出的新技术、新工艺和新设备,从沉管隧道的拓展形式、行业领域突破、助推城市建设和江河湖海沿线城市交通需求的增加等方面展望未来沉管法隧道的发展趋势。
In this paper,the application status of foundation trench excavation and navigation channel dredging,dry dock construction,element precasting,element transport,element mooring,element immersion,joint treatment and foundation treatment of several typical immersed tunnels in China are introduced. And then the Honggu Immersed Tunnel in Nanchang and subsea tunnel of island-tunnel project of Hong Kong-Zhuhai-Macao Bridge are taken as examples; and some innovations of key technologies,i. e. key construction technology,element transport and immersed technology,differential settlement control technology for element immersion,subsea connection technology,and subsea space development and subsea harbor construction technology,are summarized for river-crossing and sea-crossing immersed tunnels. Finally,the development trends of immersed tunnels are prospected based on new technologies and equipments from the aspects of prolongation of immersed tunnel,field breakthrough,urban construction promoting and traffic demand adding of cities along rivers and seas. The results can provide reference for construction and popularization of immersed tunnels.
