摘要
芜湖长江大桥因通航净空和引线高程限制 ,正桥 (连续钢桁梁斜拉桥 )设计最大坡度达到 6‰ ,斜拉桥主跨两端设置竖曲线 2处 (上、下行共计 4处 )。重点介绍明桥面竖曲线的测设和整修 。
Limited by the altitude of the navigation and the approach spans, the maximum design grade of the continuous steel truss girder cable\|stayed bridge is 6‰. Two vertical curves (4 vertical curves in all both upward and downward) shall be installed at either end of the main spans of the cable\|stayed bridge. The paper focuses on the test, installation and repair of the vertical curve of open deck to ensure the dynamic and static balance of lines on the bridge.
