英文標(biāo)題 |
Design and analysis on construction scheme of main girder of large-span steel tubular arch bridge over dual carriageway expressway |
摘要 |
針對跨雙幅高速公路大跨鋼管拱施工技術(shù)與經(jīng)濟方面存在的問題,文中提出跨雙幅大跨鋼管拱的施工方法—先梁后拱滿堂支架門洞法,提出該橋的施工支架與門洞橫梁的設(shè)計方法,并對其變形與應(yīng)力進行了分析與驗算。結(jié)果表明:此法不影響交通,適合于跨越障礙、車流量大的梁拱施工。 |
