摘要:
向莆铁路引入南昌枢纽跨九龙大道时，由于桥梁梁部建筑高度受限，以及桥梁景观等设计制约因素，经方案比选后采用108 m大跨径混凝土系杆拱桥。本文主要介绍桥梁结构形式、构造细节和施工方案，并对结构受力、动力特性、竖向刚度、拱肋稳定性和施工控制方法等进行了全面研究，重点研究了吊杆施工控制方法。通过研究和计算，将国内外新的科研成果和理论运用在本桥的设计中，进一步扩大了混凝土系杆拱结构在铁路桥梁建设上的应用，为以后类似桥梁的设计提供了借鉴。
Abstract:
Xiangpu Railway is controlled by the height of bridge beam and bridge landscape design when passes across Jiulong Road in Nanchang Hub. A tied-arch bridge with a large span of 108 m is used after the scheme comparison. The structural form of the bridge, structural details and construction scheme are mainly introduced in this paper. The structural stress,dynamic characteristics, vertical stiffness, stability of arch rib and construction control methods are comprehensively studied. The construction control method of suspender is studied emphatically. The new research achievements and theories at home and abroad are applied to the design of the bridge based on research and calculation, which has further expanded the application of the concrete tied arch structure in the railway bridge construction and provides a reference for the design of similar bridges in the future.
