京沪高速铁路六跨一联连续梁施工工艺

摘要

In recent years, the development of high-speed railway construction technology led to the development of the railway bridge. By special high-speed railway standards, strong load determine the specificity of design and construction. Bridge structure tends to large sections, large-span continuous beam, and are bulky, and generous amounts of disposable pouring concrete to complete, especially speed of 300 ~ 350 km of high-speed railway stations, turnouts and erection of prefabricated girder, the whether it is design or construction are not realistic, therefore, cast beam construction technology is widely adopted.%近年来，高速铁路的发展带动了铁路桥梁施工技术的发展。高速铁路由其特殊的高标准、强荷载决定了设计施工的特殊性。桥梁结构趋于大断面、大跨度、连续梁，而且都是大体积、大方量的混凝土一次性浇注完成，尤其是时速为300～350 km的高速铁路站台、道岔梁梁体的预制和架设，无论是设计还是施工都不太现实，因此，现浇梁施工工艺被广泛地采用。
