From July 22 to 23, 2017, the "Second National Bridge Structural Health and Safety Technology Exchange Conference and Bridge Health Monitoring, Vibration Reduction, Earthquake Resistance, Reinforcement New Technology and New Product Recommendation Meeting" was successfully held in Beijing Hengshui Building. The conference was hosted by the State Key Laboratory of Bridge Structural Health and Safety, with dozens of experts including Wang Bo of the China Railway Bridge Science Research Institute, Zeng Guangwu of the China Academy of Railway Sciences, and Ge Yaojun of Tongji University. Chairman of the company Wu Jiazheng was invited to participate in the meeting and do technical exchanges.

　　Prestressed concrete bridges are important infrastructure and a hub to ensure smooth traffic. Once a safety accident occurs, it will not only cause major losses to people's lives and property safety, but also cause some traffic networks to be paralyzed, causing bad social impacts, especially lifeline projects, which will have a particularly large impact. At the meeting, based on the research background of non-destructive testing technology for prestressed concrete bridges, Professor Wu Jiayu gave detailed technical explanations on prestressing system, grouting defects, concrete performance and defect detection, and combined with a large number of vivid and rich field engineering cases The accuracy and reliability of the theory was verified, and it was fully recognized and praised by the participants.
