This newspaper, Fuzhou, August 4th (Reporter Liu Xiaoyu) On the morning of the 4th, the first ballastless track cross-sea cable-stayed bridge of my country's high-speed railway - the newly built Fuzhou-Xiamen Railway Anhaiwan Bridge completed the ballastless track construction. The builder of China Railway Construction Bridge Bureau Successfully overcome the problem of ballastless track construction for high-speed rail cross-sea cable-stayed bridges, and achieved a major breakthrough in high-speed rail ballastless track construction.

  The Anwan Bay Bridge is one of the control projects of the newly built Fuzhou-Xiamen Railway, with a total length of 9.46 kilometers, of which the cross-sea section is 1.56 kilometers long. The main span is 300 meters, the main tower is 126.9 meters high, and it spans the 2,000-ton main channel of Anwan Bay.

For the first time in my country's high-speed railway construction, a ballastless track was laid in a cross-sea cable-stayed bridge. A high-speed train with a speed of 350 kilometers per hour crossed the bridge without slowing down, and it took less than 7 seconds to pass the 650-meter main bridge.

  The Fuzhou-Xiamen high-speed railway is the first cross-sea high-speed railway in China, with a design speed of 350 kilometers per hour and a total length of 277.42 kilometers.

After the opening to traffic, the journey from Fuzhou to Xiamen will be shortened to less than one hour, providing a strong impetus for building the "one-hour economic circle" along the coast of Fujian.
