跨双幅高速公路大跨钢管拱主梁施工方案设计与分析(51 卷) |
英文标题 |
Design and analysis on construction scheme of main girder of large-span steel tubular arch bridge over dual carriageway expressway |
摘要 |
针对跨双幅高速公路大跨钢管拱施工技术与经济方面存在的问题,文中提出跨双幅大跨钢管拱的施工方法—先梁后拱满堂支架门洞法,提出该桥的施工支架与门洞横梁的设计方法,并对其变形与应力进行了分析与验算。结果表明:此法不影响交通,适合于跨越障碍、车流量大的梁拱施工。 |
