沈阳市东塔跨浑河桥主桥方案比选

Comparison and Selection of the Main Bridge of Shenyang East Tower Bridge Across the Hun River

沈阳市东塔跨浑河桥是一座全钢结构自锚式悬索桥,为沈阳市"一河两岸"重点项目。由于桥梁横跨浑河,除满足交通通行功能外,还应具有较高的景观效果。东塔跨浑河桥跨径布置为(40+90+220+90+40)m=480m。有索区桥面宽43.3m,无索区桥面宽40m,双向8车道。主缆垂跨比为1/5.5,主缆在横桥向的间距为36m。本文介绍了该桥的设计理念以及设计方案的比选。

Shenyang East Tower Bridge across the Hun river is an all-steel structure self-anchored suspension bridge,which is the key project of“one river and two banks”of Shenyang City.As the bridge across the Hun River,in addition to meet the traffic functions,it should have a higher landscape effect.The span of East Tower Bridge is 40+90+220+90+40=480m.The width of the cable area is 43.3m wide,and the width of no cable bridge area is 40m wide,two-way 8 lanes.The main cable sag ratio is 1/5.5,the main cable in the horizontal distance of 36m.This article describes the design concept of the bridge and the design comparison.
