| 摘 要： | 湖北郧十汉江桥是一座双塔单索面预应力混凝土矮塔斜拉桥,该桥地处丹江口水库上游,主桥的孔跨布置为128 m＋238 m＋128 m,桥塔墩身最高达84.5m,主梁与桥塔连接处采用塔梁墩固接形式,不设置支座.该桥箱梁采用5.75 m大悬臂设计,有效的减轻了主梁的自重.该桥跨径较大,设计构思独特.以该桥为背景,通过计算分析郧十汉江大桥的力学行为,阐述其设计构思及静动力受力特性,可为该类桥梁的设计提供参考.

| Abstract: | The Yunshi Hanjiang River Bbridge in Hubei is a prestressed low-pylon cable-stayed bridge with two tower and single-cable- plane. Spans are attributed as 128 m ＋ 238 m ＋ 128 m. The piers reach up to 84.5m high. The Pylon-Girder-Pier are integrated,we needn＇t supports at the girder roots. The cantilever of girder is 5.75 m wide as to reduce the self-weight of main girder. It＇s a long span bridge with unique design ideas. Taking the bridge as a background, mechanical behavior and design concept are analysed through calculation and development of the special bridge is discussed. |
