The concept of connecting Zhuhai, Hong Kong and Macao has been talked about since the 1980s. The islands, bridge and tunnel will slash travel times by roughly three hours and 30 minutes, but crossing the physical barriers of the Pearl River Delta and the South China Sea is an engineering challenge like no other.
4.1英里的隧道是世界上最长的埋葬道路隧道，并在香港和桥梁之间携带六个交通岛，导致珠海和澳门，所有这些都穿过南海的一部分。该项目的岛屿和隧道部分是剧烈的混凝土结构奇迹，拥有33个隧道元件（中空混凝土和钢壳），内置于工厂。
Each tunnel piece measures 590 ft by 125 ft by 37 ft and weighs a staggering 80,000 tons. At its deepest point, the tunnel is immersed 157 ft beneath the South China Sea.
建造crews precast each element on Guishan Island, near Zhuhai, and transported them to the site by tugboats. A foundation trench in the seabed was created by general contractor China Communications Construction Co., and the massive elements—including five curved ones—arrived and were immersed into place. Gao Xinglin, assistant director and senior engineer for owner Hong Kong-Zhuhai-Macao Bridge Authority, said the concrete exteriors of the elements are “proactive water sealing closure joints,” meaning that, upon installation, all connections become waterproof. There is a 7,165-ton butt joint in the middle of the tunnel.
China Communications Construction led the joint venture engineering effort with Denmark’s COWI providing immersed tunnel expertise. Challenges included soft soil that complicated the placement of the rock bed and the sheer scale.
Artificial islands were built on each end of the tunnel in shallower waters.
中国通信建设采用了由120个空心钢的结构框架建造165英尺高，每次重550吨。它们在香港预制，在现场敲打到位，岛屿和建筑物上的建筑物围绕支持。
