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.
