摘要
文章阐述变截面连续梁出现的常见病害,分析反弯合拢束配束方式对连续梁桥的结构受力影响,并与传统配束方式进行了对比。反弯合拢束在抑制腹板、底板裂缝产生、减缓桥梁跨中下挠和减轻跨中荷载重量等方面有较好的作用,为类似桥梁设计积累宝贵经验。
This thesis elaborates the common diseases for variable continuous cross-section girder bridge and analyses the structural effects by reverse-bent steel strand for closure to continuous girder bridge, then contrasts with the general style for steel strand. The reverse-bent steel strand for closure shows better effects for preventing cracks in web & base slab, decreasing the down-warping and load weight in mid-span. This thesis also provides valuable idea for the same bridges
