The Central Committee of the Communist Party of China (CPC) and the State Council held the National Science and Technology Awards Conference 2018 in Beijing in the morning on 8th, January. Party and state leaders Xi Jinping, Li Keqiang, Wang Huning and Han Zheng attended the meeting. Professor Liao Haili from Southwest Jiaotong University attended the conference as representative of the award winners. Two projects from The School of Civil Engineering were awarded second prizes of the National Scientific and Technological Progress Awards 2018, which are the Key Technology and Engineering Application of Wind-Resistance for Long-Span Cable-stayed Bridges project held by Professor Liao Haili and the Project of Windproof and Disaster Prevention Theory, Key Technologies and Engineering Applications for Large Roof and Enclosure Systems participated by Professor Huang Guoqing.

As members of the scientific research team of this project led by Professor Liao Haili, Professor Li Mingshui, Professor Li Yongle, Professor Zheng Shixiong, Associate Professor Ma Cunming and Associate Professor Wang Qi from the School of Civil Engineering were also awarded. This award fully demonstrates that SWJTU has excellent scientific and technological innovation ability and great international influence in the field of bridge wind engineering. The project has achieved a series of innovative achievements and breakthroughs in large-scale wind tunnel test platform and test technology, wind-vibration calculation method and pneumatic control technology for long-span bridges, and independently developed the world''s largest and advanced boundary layer wind tunnel, providing key technical equipment for the wind-resistant design of long-span cable-stayed bridges. A high-precision aerodynamic model and the wind vibration analysis method for Bridges are established, and the wind-resistant design theory for Bridges is developed and improved. The aerodynamic shape design criteria for the main beam of the long-span cable-stayed bridge are established, and a systematic wind-vibration control technology is proposed. The project results have already been applied to 76 domestic and 8 foreign long-span cable-stayed bridges, including five of the world''s top ten suspension bridges, four of the world''s ten cable-stayed bridges, and see great prospects of promotion and wide application and enjoy great international competitive advantage, providing a key technical support for the long-span cable stayed Bridges construction technology into the world''s advanced ranks.
