摘　　要：景观桥梁除了能够满足人群出行的基本需求,还是城市中的地标性建筑。针对曲线外倾异形拱桥的受力特点,从总体的造型和受力模式、约束条件的设计、合理断面的选取、吊杆力的取用等角度,对影响其造型和受力的各项关键因素进行了分析,并结合某工程进行结构设计分析,有关经验可供相关专业人员参考。In addition to meeting the basic needs of people's travel,the landscape bridges are also landmarks in cities.According to the force characteristics of curved outward-inclined special-shaped arch bridges,from the perspective of the overall shape and force mode,the design of constraints,the selection of reasonable sections,and the use of boom force,the key factors affecting the shape and force of bridges are analyzed,and combined with a project,the structural design is analyzed.The relevant experience can be used as a reference for relevant professionals.
