Recently, the winners of the 2024 China Highway and Transportation Society Science and Technology Awards have been officially announced. The research project titled “Key Technologies for the Original Formation, Condition Monitoring, and Resilience Enhancement of Long-Span Arch Bridges,” completed by Professor Zhou Jianting’s team at Chongqing Jiaotong University, has been awarded the Grand Prize of the China Highway and Transportation Society Science and Technology Awards. This marks a breakthrough for our university in securing the Grand Prize in this category and is the sole Grand Prize of this year led by a university.
It is reported that the research team has dedicated over a decade to research on this topic. They have pioneered the theoretical and technical system for the original formation of long-span arch bridges, enabling precise and rapid arch formation in complex environments. The team has also independently developed multi-dimensional condition monitoring technologies and devices for long-span arch bridges, covering points, lines, and planes, achieving precise diagnosis of the overall performance of these bridges. Furthermore, they have established theories and technologies for enhancing the seismic resilience of long-span arch bridges, achieving breakthroughs in seismic analysis theory and resilience enhancement techniques.
The research findings have been successfully applied to the construction and maintenance of over 100 arch bridges, including the world's largest through-type concrete-filled steel tube arch bridge and the world’s largest double-arch bridge. These achievements have demonstrated significant economic and social benefits and possess broad application prospects.
