摘要

大跨径钢管拱桥梁主拱肋间横梁是连接左、右拱肋的主要装置,为了使左、右拱肋连接成整体,可采取钢筋混凝土横梁或钢横梁方案。通过工程实践,总结阐述了大跨径钢管拱桥梁主拱肋间钢横梁的优势,并对比分析其与钢筋混凝土横梁的经济社会效益。
        The crossbeam between the main arch ribs of the long-span steel tube arch bridge is the main device for connecting the left and right arch ribs. In order to connect the left and right arch ribs into a whole,a reinforced concrete crossbeam or a steel crossbeam scheme can be adopted. Through engineering practice,this paper summarizes and expounds the advantages of steel crossbeams between main arch ribs of long-span steel tube arch bridges,and compares and analyzes their economic and social benefits with those of reinforced concrete crossbeams.
