Wind Engineering Key Laboratory of Sichuan Province
Southwest Jiaotong University Wind Engineering Experimental Research Center, established in 1989, is one of the earliest institutes to carry out wind engineering research in China. After more than 20 years of development and construction, it has become awell-known wind engineering research institution both at home and abroad, and has formed its own characteristics and advantages in the research of wind engineering of bridges, and has trained its own scientific research team with excellent academic abilities and extensive influence at home and abroad. In September 2012, the laboratory was approved by the National Development and Reform Commission to jointly establish the National Engineering Laboratory of Land Transportation Geological Disaster Prevention and Control Technology together with Sichuan Key Laboratory of Seismic Engineering Technology. In December 2012, the laboratory was approved by the Science and Technology Department of Sichuan Province as the Key Laboratory of Sichuan Province.
1. Research Areas
1.1 Bridge aerodynamics and wind resistance safety; 2) Wind effects on building structures and wind environment; 3) Vehicle aerodynamics and operating windproof safety.
2. Test Equipment
The laboratory has a building area of about 5,000 square meters in Xipu campus and Emei campus. It has more than 20 sets of large-scale instruments and equipment (including three wind tunnels), with a total value of assets worth more than 15 million RMB.
XNJD-1 Wind Tunnelwas built in 1991 and has two test sections. The size of the first test section is 3.6m (width) × 3.0m (height) × 8.0m (length), and the wind speed range is 0.5 ~ 22.0m/s; the size of the second test section is 2.4m (width) × 2.0m (height) × 16.0m (length), and the wind speed range is 1.0 ~ 45.0m/s.
XNJD-2 Wind Tunnelwas built in 2002 and is theonlytesting wind tunnel for rain-wind induced cable vibration of cable-stayed bridges in China. The exit section size is 1.34m (width) × 1.54m (height), with the wind speed range of 0.5 ~ 20.0m/s, and the simulated rainfall range is 1mm/hr-120mm/hr.
XNJD-3 Wind Tunnelwas built in 2008 and is a key project of SWJTU’s “Tenth Five-year Plan” and “Project 211”. The test section size of the wind tunnel is 22.5m (width) × 4.5m (height) × 36m (length), and the wind speed range is 1.0 ~ 16.5m/s. It is the largest borderline wind tunnel in the world, which can simulate the effect of the earth surface’s strongest natural wind on the engineering structure, and its main technical indicators reach the world’s leading level.
In addition, the laboratory also has a complete range of test equipment such as electronic pressure scanner, non-contact strain displacement analysis and measurement system, cobra three-dimensional pulsating anemometer, laser displacement measurement and analysis system, conventional force balance, high frequency force balance, and synchronous dynamic pressure measuring system, etc., which can satisfy the need of wind tunnel test for bridges, buildings, etc.

3. Scientific Research Achievements
The laboratory has undertaken more than 60 national projects including 973 Program, National Science and Technology Support Program, NSFC, etc., and more than 80 scientific research projects at ministerial level, including Western Transportation Construction Science and Technology Project of Ministry of Transport, Science and Technology Research and Development Program of Ministry of Railways, and Transportation Science and Technology Project of Sichuan Province, and more than 200 applied technology projects in the fields of architecture, large span bridge, vehicle and locomotive. In the past five years, we have published more than 500 research papers in international and domestic academic journals (including more than 100 papers in SCI journals), submitted application for over 40 patents for invention, and won more than 20 scientific and technological progress awards.
The laboratory has not only provided support of anti-wind safety to national major engineering projects such as Zhoushan Island-Land Project, Hong Kong-Zhuhai-Macao Bridge, Shanghai-Nantong Combined Yangtze River Bridge, Yangsigang Yangtze River Bridge, Pingtan Strait Road-rail Bridge, Shenzhen-Zhongshan Lingdingyang Bridge, etc., but also successively undertaken wind tunnel tests for international bridge engineering projects such as Sumalatu Bridge in Indonesia, Stone Cutters Bridge in Hongkong, Sultan Abdul Halim Bridge in Malaysia, Kigamboni Bridge in Tanzania, Maputo·Katembe Bridge in Mozambique, Gerald Desmond Bridge in the US, China-Maldives Friendship Bridge, Halogaland Suspension Bridge in Norway, and the 1915 Chanakale Bridge in Turkey, etc.
