摘　　要：为提高竹拱桥的跨越能力,以我国已建成的最长竹桥——玲珑大桥为启发,提出采用圆竹和钢材进行多跨连续圆竹-钢组合拱桥的全预制快速拼装建造方法,系统研究圆竹的调弯、防腐工艺和拱圈、拱上建筑的预制拼装,以及拱圈的变形控制等关键技术。结果表明:圆竹-钢组合拱桥的跨越能力明显优于竹拱桥,且结构变形较小;该桥型的构件全部采用预制拼装,具有造价低、施工快速、节能环保等优点,研究结果可为圆竹-钢组合拱桥在类似工程中的推广应用提供参考。To improve the spanning capacity of bamboo arch bridge,inspired by the longest bamboo bridge in China,namely Linglong Bridge,a multi-span continuous bamboo-steel composite arch bridge was proposed to be constructed by full prefabricated and rapid assembly of round bamboo and steel,such as bending adjustment and anti-corrosion,as well as the key construction technologies,such as the assembly of round bamboo-steel composite arch bridge and buildings on the arch,and the deformation control of arch ring were systematically studied in this paper.The results showed that the spanning capacity of the round bamboo-steel composite arch bridge was obviously better than that of the bamboo arch bridge,and the structural deformation was small.The components of the bridge were all prefabricated and assembled,which had the advantages of low cost,fast construction,energy saving,and environmental protection.The research results can provide reference for the popularization and application of round bamboo-steel composite arch bridge in similar projects.
