| 吊裝施工中扁平鋼箱梁段橫向變形研究(51 卷) |
| 英文標(biāo)題 |
| Study on transverse deformation of flat steel box girder during bridge-erecting construction |
| 摘要 |
| 在大跨斜拉橋扁平鋼箱梁吊裝施工過(guò)程中，被起吊梁段和吊機(jī)作用梁段橫向變形相反，造成梁段對(duì)接困難。本文以典型獨(dú)塔雙索面扁平鋼箱梁斜拉橋?yàn)楣こ瘫尘?，利用三維有限元模型，分析了均勻溫度變化、梯度溫度變化、縱隔板位置、縱隔板剛度對(duì)吊裝施工中扁平鋼箱梁橫向變形差的影 |
