China’s High-speed Rail Succeeds in Maintaining Its Original Speed When Crossing Sea and Bridges
4日上午，我国高铁首座无砟轨道跨海斜拉桥——新建福厦铁路安海湾特大桥完成无砟轨道施工，中国铁建大桥局建设者成功攻克高铁跨海斜拉桥无砟轨道施工难题，取得高铁无砟轨道施工重大突破。
On August 4th, China’s first cross-sea cable-stayed bridge over ballastless track - the new Fuxia Railway Anhai Bay Huge Bridge completed the construction of ballastless track. Builders of the China Railway Construction Bridge Bureau successfully overcome the construction problem of ballastless track of the high-speed rail cross-sea cable-stayed bridge, making a major breakthrough in the construction of the ballastless track of the high-speed rail.
安海湾特大桥是新建福厦铁路全线控制性工程之一，全长9.46公里，其中跨海区段长1.56公里，主桥为双塔双索面半漂浮体系钢-混结合梁斜拉桥，主跨300米，主塔高126.9米，跨越安海湾2000吨级主航道。在我国高铁建设中首次在跨海斜拉桥中铺设无砟轨道，时速350公里高铁列车跨海过桥不减速，驶过650米主桥用时不到7秒。
Anhai Bay Huge Bridge is one of the control projects of the whole line of the new Fuzhou-Xiamen Railway, with a total length of 9.46 kilometers, of which the cross-sea section is 1.56 kilometers long, and the main bridge is a double-tower double cable-surface and semi-floating system steel-mixed girder cable-stayed bridge, with a main span of 300 meters, the main tower height of 126.9 meters, and a 2,000-ton main channel across Anhai Bay. It’s the first time that China laid ballastless track in the construction of China's high-speed rail in the cross-sea cable-stayed bridge, the speed of 350 kilometers per hour high-speed rail train across the sea across the bridge does not slow down, driving over the 650 meters of the main bridge takes less than 7 seconds.
福厦高铁是国内首条跨海高铁，设计时速350公里，全长277.42公里。通车后，福州至厦门行程缩至1小时内，为打造福建沿海“一小时经济圈”提供强劲动力。
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 opening, the trip from Fuzhou to Xiamen has been reduced to 1 hour, providing a strong impetus for building a “one-hour economic circle” along the coast of Fujian.
