“桦加沙”过境珠江，能扛17级台风的超级工程怎样了

Core Viewpoint - The article discusses the rapid development of the Guangdong-Hong Kong-Macao Greater Bay Area through major engineering projects, emphasizing the importance of wind resistance in bridge design due to the region's susceptibility to super typhoons [2][3]. Group 1: Engineering Projects - The Huangmaohai Cross-Sea Channel, which began construction in June 2020 and is set to open in December 2024, is a key project connecting Zhuhai and Jiangmen, featuring a main span of approximately 700 meters [3][5]. - The Shenzhong Channel, which includes the Shenzhong Bridge, is noted as the world's most complex cross-sea engineering project, integrating bridge, island, tunnel, and underwater connections [6][7]. Group 2: Wind Resistance Technologies - Advanced technologies such as "wind nozzles + vortex plates + central stabilizing plates" and "horizontal wing plates + vortex suppression grids" have been developed to enhance the wind resistance of large-span bridges [6][8]. - The Huangmaohai Cross-Sea Channel has conducted the world's first full-bridge vortex wind tunnel test, demonstrating superior wind resistance performance compared to international comfort standards [6][7]. Group 3: Recent Typhoon Impact - Typhoon "Hua Jia Sha," classified as a super typhoon, impacted Guangdong with wind speeds reaching 52 meters per second, prompting extensive safety measures and inspections across various bridge projects [9][10]. - The Guangdong Transportation Group mobilized over 9,396 personnel for pre-typhoon inspections and implemented temporary closures of major bridges, including the Hong Kong-Zhuhai-Macao Bridge [9][10].
