摘　　要：传统钢筋混凝土系杆拱桥,因其结构受力合理,造型美观,在中小跨径桥梁中得到普遍应用。随着系杆拱桥的大量应用,尤其是有景观需求的城市桥梁,对外观创新提出了更高要求。结合传统钢筋混凝土系杆拱桥,积极探索通过设计副拱顺接主拱拱轴线形,使其过渡流畅,增强视觉美感。The traditional reinforced concrete tied arch bridge is widely used in medium and small span bridges because of its reasonable structure and beautiful shape.With the wide application of tied arch bridge,especially the urban bridge with landscape demand,the appearance innovation has put forward higher requirements.Combining with the traditional reinforced concrete tied arch bridge,this paper actively explores how to connect the main arch axis through the design of the auxiliary arch to make the transition smooth and enhance the visual beauty.
