摘要
文章介绍了港珠澳大桥珠海连接线工程中控制性工程——拱北隧道下穿口岸段隧道结构形式及施工方案论证的比选过程。根据实际工程调研及设计经验,提出了封闭管幕保护下的浅埋暗挖方案;并研究和分析了管幕工法的设计施工要点和难点,以及应采取的对策和措施。
This paper introduces the option selection regarding the structure type and construction methods of the Gongbei tunnel,the key project at the Zhuhai link of the Hong Kong-Zhuhai-Macao Bridge.Based on the project investigation and design experience,the shallow mined method combined with an enclosed pipe-roof is recommended.This paper analyzes the key points and potential difficulties of design and construction of the pipe-roof as well as the relevant countermeasures.
