摘要
为促进我国高速铁路桥梁的建设发展,在回顾该类桥梁的发展历程和成就的基础上,对该类桥梁的设计技术进行总结和探索。分析常用跨度简支箱梁的动力性能和后期变形控制、大跨度混凝土梁式桥及组合结构的设计参数和极限跨度、大跨度上承式拱桥的结构形式和施工方法等关键技术;研究大跨度斜拉桥主梁的竖向刚度、横向平面曲线半径、梁体扭曲、梁体扭转等主要参数取值;开展铁路悬索桥应用的探索,提出大跨度缆索支承桥梁的运行速度、合理刚度等亟待解决的问题。从设计理论、材料、结构形式、装备和施工工艺等方面提出我国高速铁路桥梁的发展方向。
In order to promote the construction and development of the high-speed railway bridges in China,the design techniques of this kind of bridges were summarized and explored on the basis of reviewing the development history and achievements of the bridges.Key techniques such as the dynamic performance and later-period deformation control of the common span simply supported box girders,the design parameters and limit span of the long-span concrete girder bridges and composite bridges,the structural forms and construction methods of the long-span deck type arch bridges were analyzed.The main parameters such as the vertical rigidity,transverse plane curve radius,beam twist and beam torsion of the main girders of the long-span cable-stayed bridges were studied.The exploration of the application of the railway suspension bridges was carried out,and the problems to be solved urgently,such as the operating speeds and reasonable rigidity of the long-span cable-supported bridges were proposed.The future development directions of the high-speed railway bridges in China were proposed through the aspects of the design theory,material,structural form,equipmentand and construction technology.
