Why is Chongqing the "Bridge Capital" of China?
The name of "Bridge Capital" in Chongqing has a long history. In 2005, Chongqing was identified as China's "Bridge Capital" by the Bridge Committee of Beijing Mao Yisheng Science and Technology Education Foundation, an authority in China's bridge industry.
Chongqing is also recognized as the "Capital of Ten Thousand Bridges" at home and abroad.
Liu Qiang, vice president of Chongqing Bridge Association and chairman of Chongqing Nachuan Engineering Technology (Group) Co., Ltd., said that Chongqing has a large number of bridges, large scale and high technical indicators.
At present, over 15,000 bridges of various types have been built in Chongqing, and 128 extra-large bridges have been built in the Yangtze River, Jialing River and Wujiang Chongqing Region, including various types of bridge structures, of which four are world-leading in terms of technical indicators.
"Chongqing people build roads and bridges when they meet mountains and waters." Liu Qiang said that Chongqing's special landforms (surrounded by the Yangtze River, Jialing River, Wujiang River, etc., with mountainous terrain) have prompted the vigorous development of bridge construction. After more than half a century of unremitting efforts, Chongqing From an inconvenient inland mountain city, it has become China's "bridge capital" extending in all directions.
For 19 years, Lai Yaping, deputy chief engineer of bridges of TYLI International Engineering Consulting (China) Co., Ltd., participated in or presided over the design of more than 20 large or extra-large bridges of various types, many of which are bridges in Chongqing.
"Chongqing's bridges are not easy to build." Lai Yaping said that the steep and steep terrain features and unique natural environment determine that Chongqing's bridge construction is more difficult than plain cities in terms of design and construction. and challenges.
Lai Yaping said that the difficult factors of bridge construction include but are not limited to: terrain restrictions, navigation requirements, technical conditions, economic performance, landscape features, and the fluctuation of the water level in the Three Gorges Reservoir area.
How does China's "Qiaodu" "out of the circle" in the world?

Chen Wanzhi introduced that by the end of 2020, the total number of bridges in China has exceeded 1 million, and the bridge design life is 100 years. There is a huge demand for bridge maintenance technical services and personnel training.
Chen Wanzhi believes that it is possible to build the China Bridge Museum in Chongqing, establish China Bridge Big Data Center, establish China Bridge Construction and Maintenance Technology Research Institute, establish China Bridge Maintenance Hospital, seize the international market bridge construction and maintenance technology highland, and promote international high-end bridges The R&D, promotion and application industries of new materials, new technologies, new processes and new equipment for construction and maintenance projects are distributed in Chongqing, forming a new economic and tourism growth point in Chongqing.
