摘要
介绍了广珠城际快速轨道交通工程西江特大桥主桥桥式方案的构思,通过研究比选,采用100 m+2×210 m+100 m独塔斜拉连续刚构组合桥式方案。该桥式结构新颖、刚度条件好且经济美观,在现代高速铁路桥梁中不失为较佳桥型方案之一。
The conceptual consideration for bridge type of the main bridge of Xijiang River Bridge on Guangzhou-Zhuhai Intercity Rapid Rail Transit are presented. Through the research and comparison, the single pylon continuous cable-stayed rigid-frame hybrid girder bridge with span arrangement 100 m＋2×210 m＋100 m is adopted. The adopted type of the bridge is structurally novel, its rigidity conditions are good and the bridge is economic, aesthetic, and yet it is one of the good types of modern bridges for high speed railways.
