雄忻高铁全线控制性工程北太行山隧道全线贯通

Core Viewpoint - The successful completion of the Beitaihang Mountain Tunnel marks a significant milestone for the Xiongxin High-Speed Railway, establishing a solid foundation for its timely operation, enhancing transportation links between Hebei and Shanxi provinces [1][2]. Group 1: Project Overview - The Beitaihang Mountain Tunnel, part of the Xiongxin High-Speed Railway, spans 12.519 kilometers with a maximum depth of 600.96 meters and a minimum depth of 20 meters, classified as a high-risk tunnel due to geological challenges [1]. - The tunnel construction faced various geological risks, including water and mud bursts, rock explosions, collapses, and fault zones, necessitating advanced construction techniques and safety measures [1]. Group 2: Technological and Environmental Measures - The construction team employed advanced technologies such as advanced geological forecasting, monitoring, and digital control systems to enhance safety and efficiency during the tunneling process [1][2]. - To adhere to environmental protection standards, wastewater treatment facilities were established near tunnel entrances and mixing stations, ensuring that wastewater is treated to meet regulatory standards before discharge [2]. Group 3: Economic and Social Impact - The Xiongxin High-Speed Railway, stretching approximately 342 kilometers, is a crucial part of China's "Eight Vertical and Eight Horizontal" high-speed rail network, significantly improving transportation connections between Shanxi and the Beijing-Tianjin-Hebei region [2]. - The completion of this railway project is expected to promote economic and social development along the route and facilitate regional collaborative growth [2].
