客运专线铁路双线圆端形空心桥墩施工技术

Construction Technology of Circular Hollow Bridge Pier of Double-track for Passenger Dedicated Railway Line

客运专线建设是实现我国铁路跨越式发展的需要,时速350km客运专线在我国尚没有成熟的经验,只有在施工过程中精心组织,仔细摸索,不断总结,才能提高施工质量。结合武汉天兴洲长江大桥北岸引桥客运专线铁路双线圆端形空心桥墩施工的工程实践,对客运专线铁路空心墩施工的方法、工艺过程及施工效果进行了介绍。

Achievement of the great-leap-forward development of country railway is needed to construct passenger dedicated railway line. The plan and careful grope are elaborated and the result is summarized to improve the quality on the project, because there is no mature experience on the 350 km/h special railway for passenger dedicated railway line. Based on the circular hollow bridge pier in passenger dedicated railway line of Wuhan Tianxingzhou at north Yangtze River Side Bridge, construction technology and process of circular hollow bridge pier are introduced as well as construction effects.
