摘要
济南市凤凰路黄河大桥北侧跨大堤引桥为主跨跨径为245 m的组合钢箱梁桥,跨度在国内目前同类桥梁中排名第一.本研究对该组合梁桥的连续梁负弯矩区桥面板、双层组合结构设计进行了分析研究,体现了设计与施工相结合的理念,提高了大跨度连续组合箱梁的技术与经济竞争力.
Abstract
With the main span length of 245m,the approach bridge across embankment on the north side of the Yellow River Bridge on Fenghuang Road in Jinan is a combined steel box girder structure,ranking the first of its kind in China up to date.The design of bridge panel and double-layer composite structure in the negative bending moment area of continuous beam is analyzed and studied in the paper,which reflects the concept of combining design and construction.The research improves the technical and economic competitiveness of long-span continuous composite box girder.
