杭衢高铁启动联调联试 年底有望开通运营

Core Viewpoint - The new Hangzhou to Quzhou high-speed railway (Hangzhou-Quzhou High-speed Railway) has entered a critical phase with the initiation of joint debugging and dynamic testing, expected to be operational by the end of this year [1] Group 1: Project Overview - The Hangzhou-Quzhou High-speed Railway is the first high-speed railway in China to operate under the "PPP+EPC" model [1] - The railway spans approximately 131 kilometers with a design speed of 350 kilometers per hour, featuring six stations including JianDe (existing), JianDe South, and LongYou North [1] - The project has a high bridge-tunnel ratio of 78.7% [1] Group 2: Construction Progress - The construction of the project began in May 2020 and is set to complete various phases by 2025, including tunnel completion in January 2024 and track laying by April 2025 [6] - Key engineering challenges were overcome during construction, including the construction of the Changshan River Grand Bridge, which has the largest span of 240 meters among domestic high-speed rail three-line low-tower cable-stayed bridges [6] - The project emphasizes environmental protection, particularly in the construction of the Xin'an River Grand Bridge, which crosses a first-level water source [6] Group 3: Testing and Future Impact - The joint debugging phase will involve comprehensive testing of traction power supply, communication signals, and track bridge systems to ensure operational standards are met [6] - Once testing is completed, the line will transition to a trial operation phase [6] - The completion of the Hangzhou-Quzhou High-speed Railway is expected to enhance the regional railway network layout and contribute to the integrated development of the Yangtze River Delta [6]
