西陵长江大桥——我国首座大跨度全焊接钢箱梁现代悬索桥

西陵长江大桥为三峡水利枢纽工程前期准备工程中的一项重要的交通设施.为我国继汕头海湾大桥之后,独立完成的第二座跨度更大的现代悬索桥.1993年完成初步设计,1994年初正式开工,历时仅31个月基本建成,1996年8月10日开通使用,其工期之短实属罕见.本文重点介绍其技术成就、工程规模、全焊接正交异性板钢箱梁构造、主缆编制及锚固型式等工程概况,以及悬索桥的结构特征.

XILING YANGTZE RIVER BRIDGE THE FIRST LONG SPAN SUSPENSION BRIDGE WITH ALL-WELDING STEEL BOX GIRDER IN CHINA

Xiling Yangtze River Bridge is one of the important traffic facilities for preparation of the Three-Gorge Water Conservancy Key Project. It is the second longer span modern suspension bridge which was independently com pleted without foreign technical participation after Shantou Bay Bridge. Its preliminary design was finished in 1993, and construction work was formally commenced in the beginning of 1994. Fundamental construction period was only 31 months before it was opened to use on 10 Aug. 1996. This short construction period was scarcely found in the world. The paper mainly describes the technical achivement, engineering extent, construction of all-welding steel box girder with orthotropic steel deck plate, cable fabrication and its structural anchor type, as well as the structural characteristics of the suspension bridge.
