摘　　要：连续钢箱梁桥较拉索支撑扁平流线型钢桥跨径小且刚度大。现有的钢桥面铺装结构主要适应于拉索支撑扁平流线型钢桥铺装,而连续钢箱梁桥面铺装结构体系的研究在国内尚属空白,依托南通市九圩港大桥提出新型桥面铺装结构并进行针对性设计,运营通车以来尚未出现任何病害,表现出良好的使用性能,进一步的跟踪观测正在进行中。Compared with the cable support flat streamlined steel bridge,the span of the continuous steel box girder bridge is smaller and its rigidity is higher.The deck pavement structures of the existing steel bridges are mainly suitable for the pavement of the cable support flat streamlined steel bridge.However,the study on the continuous steel box girder deck pavement structure is still blank in China.Based on Jiuweigang Bridge of Nantong City,the article puts forward the novel deck pavement structure and carries out the special design.Since the traffic put into operation,there is no any faults and the service performance is good.The further follow-up observations are in progress.
