On the evening of April 17th, after conducting load tests with a convoy of 136 heavy trucks with a total weight of approximately 5000 tons, the Lingdingyang Bridge of the Shenzhen-Zhongshan Corridor successfully completed its static and dynamic load tests. This marks the world's first completion of load tests on an extra-large-span suspension bridge entirely over open sea waters.

In a relevant report by Shenzhen TV, the research and development team from the Smart Optical Measurement Research Institute at Shenzhen University demonstrated their technical expertise and professional dedication during the static and dynamic load tests of the bridges (Zhongshan Bridge and Lingdingyang Bridge) on the Shenzhen-Zhongshan Corridor. Under the leadership of Academician Qifeng Qi and Professor Xiaolin Liu, the large-scale engineering structure photogrammetric measurement team utilized their innovative serial-parallel flexible camera network technology. This technology replaced traditional communication pipes and GNSS systems. By deploying a serial-parallel flexible camera network system, they could dynamically and accurately monitor the displacement of bridge structures in real-time. This provides a scientific basis and support for the completion acceptance and future maintenance decisions.

Assistant Professor Hu Biao, Postdoctoral Fellow Dr. Yin Yihe, Dr. Chen Wenjun, Dr. Zhang Qiang, Dr. Sun Dianjun, and 6 others tirelessly worked for over 10 consecutive days in challenging conditions. Through their diligent efforts, they successfully completed the static and dynamic load tests of the Zhongshan Bridge and Lingdingyang Bridge on the Shenzhen-Zhongshan Corridor, achieving a measurement accuracy of 1mm within a kilometer-scale deformation of the main beam. Their work has been recognized by the Shenzhen-Zhongshan Corridor Management Center. This system will continue to play a crucial role in the subsequent structural health monitoring system for monitoring the deformation of bridge structures.
