The Hong Kong-Zhuhai-Macao Bridge is a mega sea-crossing passage connecting Hong Kong, Zhuhai, and Macao, with a total length of 55 kilometers. Located in the typhoon-prone area of China, it experiences over 200 days of wind exceeding force 6, over 100 days of wind exceeding force 7, and over 30 days of wind exceeding force 8 each year. Additionally, it faces approximately two typhoon strikes annually. Apart from the main beam bridge span of the Jiuzhou Channel Bridge, which has a bridge deck height of 47.5 meters above the water surface, the remaining parts of the bridge have deck heights exceeding 80 meters. Crosswinds pose significant safety risks for vehicle traffic.
To mitigate the impact of crosswinds on driving vehicles, the road wind barrier technology developed by Shangfeng Technology was employed. Road wind barriers, 2.5 meters in height, were installed on both sides of the road to effectively reduce wind speed, eliminate the impact of strong winds on driving vehicles, and provide a safety barrier for the Hong Kong-Zhuhai-Macao Bridge. After completion of the project, it has successfully withstood tests from typhoons of up to force 16, demonstrating significant effectiveness in wind resistance.
