摘要
阐述了九江至南昌城际轨道交通修水特大桥主桥桥式方案的构思,该桥受线路条件控制,要求尽量采用较低梁高的桥式方案,通过研究比选,设计推荐采用(32+140+32)m钢箱刚架拱桥式方案。重点介绍该桥式结构的总体设计和结构分析。
The conceptual consideration of bridge type for the main bridge of Xiushui Bridge on the Intercity Rail Transit from Jiujiang to Nanchang are described . Limited by the Transit alignment, the Bridge is required to be designed as a one with possible shallower girders. On the basis of the research and comparison of the bridge type alternatives, the steel box rigid-frame arch bridge with span arrangement （32＋140＋32） m is recommended for the main bridge of the Bridge in the design. In this paper, the overall design and structural analysis of the bridge are mainly dealt with.
