Today, the Lingdingyang is still hazy, but a sea-crossing dragon has been born. The Hong Kong-Zhuhai-Macao Bridge spans the Lingdingyang Ocean, connects Hong Kong in the east, Zhuhai and Macau in Guangdong in the west, and has a total length of about 55 kilometers. The Hong Kong-Zhuhai-Macao Bridge project demonstrates the superb wisdom of the Chinese people in the field of bridge engineering and reflects the country’s comprehensive strength.
Advantages of aluminum bridge
The Hong Kong-Zhuhai-Macao Bridge bridge project uses 425,000 tons of steel, about 60 Eiffel Towers, and is the first such project to use steel box beams on such a large scale worldwide. Although the steel structure of such a large tonnage bridge is the first choice, compared to steel, aluminum alloy materials have a lower density and lighter weight, only 34% of the same volume of steel, and the strength index is basically the same as steel. At the same time, it has excellent elastic modulus and good anti-corrosion performance, and the structure maintenance cost is low, so it has been widely used in modern bridge construction.
History of aluminum bridges
Aluminum alloy bridges have a long history abroad. Between 1949 and 1985, about 35 aluminum alloy structural bridges were built in the United Kingdom, while Germany also built about 20 aluminum alloy structural bridges from 1950-1970. The construction of a large number of bridges has provided valuable experience for future generations to build aluminum alloy bridges.
