摘要
芜湖长江大桥 ,是一座公路、铁路两用桥 ,在极其恶劣的环境条件下 ,采用了跨径为 (180 +312 +180 )m的斜拉桥 ,其特点为塔矮 ,塔高与中跨跨径之比为 0 .11,边跨跨径大 ,边跨与中跨的比值 0 .5 77,铁路荷载很大 ,动力作用大 ,提高梁的刚度 ,采取了三点措施 ,以满足铁路运行的需要 .
The Wuhu Yangtze River Bridge is a combined rail and highway double deck bridge. It is a cable stayed bridge with a 312?m center span and two 180?m side spans. The bridge is featured for the relatively low pylons, the ratio of pylon height to span length is 0.11, the length ratio of side to main span is as high as 0.577, dynamic effect induced by heavy live load of railway makes it necessary to improve stiffness of the girder, three measures are taken to satisfy requirements of railway operation.
