China's bridge construction has made remarkable achievements in the past few decades. From cross-sea bridges to mountain canyons, Chinese engineers continue to challenge the limits of nature and create one world-class bridge miracle after another. Today, we will introduce several of China's most representative bridges, which are not only the pinnacle of engineering technology, but also a symbol of China's infrastructure construction strength.
Beipanjiang Bridge in Guizhou: A giant dragon in the sky
Beipanjiang Bridge is currently the highest bridge in the world, spanning the two provinces of Yunnan and Guizhou. The bridge is 1,341.4 meters long, with a main span of 720 meters. The bridge deck is 565 meters above the valley floor, equivalent to a 200-story building. What is amazing is that the entire bridge uses only 224 cable-stayed cables to suspend the tens of thousands of tons of bridge deck at an altitude of more than 500 meters.
The construction of Beipanjiang Bridge overcame multiple challenges such as complex terrain and extreme climate. Engineers have adopted advanced wind and earthquake-resistant technologies to ensure the safety of the bridge. Driving on the bridge gives people a wonderful feeling of flying in the clouds. This bridge is not only a major traffic route, but also a famous tourist attraction.
Ganhaizi Bridge on Ya'an-Xichang Expressway in Sichuan: The Great Wall of Steel
Ganhaizi Bridge on Ya'an-Xichang Expressway is the world's longest steel tube cross-beam highway bridge, with a total length of 1,811 meters. The uniqueness of this bridge is that it is built entirely of steel tubes and can withstand a magnitude 9 earthquake, creating 7 world firsts.
The design of Ganhaizi Bridge fully considers local geological conditions and environmental factors. Engineers have adopted innovative structural design and construction methods, which not only ensures the strength and stability of the bridge, but also greatly shortens the construction period. This "highway in the clouds" has become a model of technological innovation in China's bridge construction.
Hong Kong-Zhuhai-Macao Bridge: A cross-sea miracle
The Hong Kong-Zhuhai-Macao Bridge is the world's longest cross-sea bridge, with a total length of 55 kilometers, connecting Hong Kong, Zhuhai and Macao. The construction investment of this bridge is as high as 126.9 billion yuan, creating more than 600 patents. Its completion marks that China has reached the world's top level in the field of bridge construction. The design life of the Hong Kong-Zhuhai-Macao Bridge is as long as 120 years, which is extremely rare in bridge engineering. In order to cope with the complex marine environment, engineers have adopted a number of innovative technologies, such as immersed tube tunnels and artificial islands. After the bridge was opened to traffic, it was hailed as the first of the seven wonders of modern times, fully demonstrating China's engineering and technical strength.
