摘要
港珠澳大桥沉管隧道是中国第一条外海深埋沉管隧道,拥有其他隧道中不一样的特点及施工难点,在路面设计过程中,应从众多的因素中找到制约路面的边界条件进行针对设计。文中主要基于港珠澳大桥沉管隧道路面方案设计过程中所经历的初步设计、深化设计等阶段,通过持续对沉管隧道运行机理的认知和理解,参考国外类似的工程及行业内的发展状况,综合比选采用了适合于该工程的路面设计方案。
The immersed tube tunnel of the Hong Kong-Zhuhai-Macao Bridge is the first offshore deep-buried immersed tunnel in China,with characteristics and difficulties different with other tunnels.During the design of the road pavement,the boundary conditions that restrict the pavement should be found out from numerous factors for design.This article is mainly based on the preliminary design,indepth design,and other stages during the design process,through the continuous understanding to the operation mechanism of the immersed tunnel,and referring to similar projects overseas and within the industry,the pavement design scheme is determined after comprehensive comparisons.
