In June 2024, the Luhong River Grand Bridge—a key controlling structure of the Shaoyang–Yongzhou High-Speed Railway—successfully achieved closure, marking a significant milestone in the project’s construction. Spanning approximately 2.3 kilometers, the bridge features a continuous girder main span that crosses the Luhong River and vital roadways on both banks, presenting considerable technical challenges. To ensure quality and safety, the construction team employed intelligent monitoring systems and Building Information Modeling (BIM) technology throughout the process, overcoming complex geological conditions and flood-season constraints. The Shaoyang–Yongzhou High-Speed Railway is an integral part of China’s national ‘Eight Vertical and Eight Horizontal’ high-speed rail network, linking Shaoyang and Yongzhou in Hunan Province with a design speed of 350 km/h. Upon completion, it will significantly reduce travel time between the two cities, boost socio-economic development in southern Hunan, and enhance regional tourism integration. The successful closure of the bridge paves the way for subsequent track-laying and system testing, laying a solid foundation for the line’s timely opening.
2024年6月，邵永高铁关键控制性工程——跨芦洪江特大桥顺利实现合龙，标志着该高铁项目建设取得重大阶段性进展。芦洪江特大桥全长约2.3公里，主跨采用连续梁结构，跨越芦洪江及两岸交通要道，施工难度大、技术要求高。为确保工程质量和安全，建设单位采用智能监测系统与BIM技术进行全过程管控，并克服了复杂地质条件和汛期施工等多重挑战。邵永高铁是国家‘八纵八横’高速铁路网的重要组成部分，连接湖南邵阳与永州，设计时速350公里，建成后将大幅缩短两地通行时间，促进湘南地区经济社会发展和旅游资源整合。此次大桥合龙不仅为后续铺轨和联调联试创造了有利条件，也为全线按期通车奠定了坚实基础。
