| 摘 要： | 贵州镇胜公路北盘江大桥为典型山区的特大桥梁,桥址建桥条件复杂,主桥采用主跨636m的钢桁梁悬索桥。介绍工程概况及桥面系现状,并重点论述桥面系的选型、连续长度的比选、构造及与主桁的连接措施。针对桥址山区特殊的风环境,通过研究,采用636m通车无缝的连续钢桥面系,既增加主梁的整体刚度,减少横风作用下主桁杆件内力,又节省造价,且行车平顺,运营良好。

| Abstract: | Beipanjiang bridge on Zhensheng road in Guizhou province is a typical large mountain bridge. The construction conditions of bridge site are very complex. The main bridge adopts steel truss girder suspension bridge with main span of 636 m. The article introduces project overview and deck system situations, and focuses on the selection of deck system, comparison of continuous length, structure and the connection arrangement of main truss. In light of the wind environment in the area of bridge site, a steel br... |
