摘要:

中国西部地区包括新疆、青海、甘肃、宁夏、陕西、西藏、云南、贵州、四川、重庆、广西及内蒙古12个省、市、自治区,面积达672×10⁴ km²,占中国国土总面积的65%左右; 西部地区山地面积约400×10⁴ km²,占中国山地总面积624×10⁴ km²的65%左右。西部地区山峦重叠、沟壑纵横、沟深谷幽、戈壁大漠的地形地貌使西部地区的风环境和桥梁结构具有和中国东部、中部地区显著不同的特点。就西部地区风环境和桥梁结构的特点,论述了西部地区桥梁风工程应予以研究的内容和问题,并介绍了相关的风环境观测和风洞试验研究。

Abstract:

There are 12 provinces, cities and autonomous regions in the western area of China, including Xinjiang Uygur Autonomous Region, Qinghai Province, Gansu Province, Ningxia Hui Autonomous Region, Shaanxi Province, Tibet Autonomous Region, Yunnan Province, Guizhou Province, Sichuan Province, Chongqing, Guangxi Zhuang Autonomous Region, and Inner Mongolia Autonomous Region. The total area amounts to 6.72 million square kilometers, accounting for about 65% of the national area. The mountainous region area is approximately 4 million square kilometers in the western area, accounting for about 65% of the total mountainous region area in China. In western area, the wind environment and bridge structure are different from those in other areas of China because of the large amount of overlapping mountains, deep ditches and great deserts. Authors discussed the research content of wind project aimed at the wind environment and bridge structure in western area, and also introduced the related wind environment measurement on-site and the wind tunnel tests.
