通苏嘉甬高铁跨苏虞张公路项目关键性控制工程取得突破

Group 1 - The completion of the continuous beam for the Tong-Su-Jia-Yong High-Speed Railway marks a significant breakthrough in the project's key control engineering, laying a solid foundation for subsequent construction phases [1] - The continuous beam spans 273.7 meters with a configuration of (72+128+72) meters, and is the largest span continuous beam in the project, highlighting its importance as a core control engineering component [1] - The construction involves complex operations such as high-altitude work and three-dimensional cross operations, which present challenges in terms of construction duration, technical difficulty, and safety risks [1] Group 2 - The Tong-Su-Jia-Yong High-Speed Railway is a crucial part of the national high-speed railway network and serves as an important north-south artery for the Suzhou "Feng" shaped national trunk railway network [2] - Upon completion, the railway will connect with several existing lines, significantly enhancing north-south transportation efficiency in the Yangtze River Delta region and injecting new momentum into regional economic development [2]
