摘　　要：贵州镇胜公路北盘江大桥为典型的山区特大桥梁,桥址建桥条件复杂,主桥采用主跨636 m的钢桁梁悬索桥。主要介绍该桥的支承体系设计、加劲梁设计、桥塔与基础设计、锚碇及缆索体系设计及主要技术特点,论述加劲梁梁段架设及连接、钢桥面系的设置方式以及峡谷地区风场环境与结构抗风等问题。Beipan River Bridge on Zhenning-Shengjingguan Expressway in Guizhou is a typical mountainous region major bridge. The construction conditions at the Bridge site are complex and the 636-m main span steel truss girder suspension bridge is therefore selected for the main bridge of the Bridge. This paper mainly deals with the design and principal technical features of the supporting system, stiffening girder, towers, foundations, anchorages and cable system of the bridge and describes in detail several issues on the erection and connection of the stiffening girder blocks, ways of the steel floor system arrangement, wind field environment and structural wind resistance in the canyon area.
