摘　　要：异型拱桥因其姿态多变,在城市景观桥梁建设中应用较多。跨临港大道景观桥采用横向非对称、纵向偏态拱型式,主跨130 m,主梁为分体双箱弧形梁,中间以横梁联系。文章对其结构设计、施工控制和计算分析做全面介绍,总结了该类桥梁的结构特点和受力特性,并提出了改善其受力性能的方法,可为类似项目的设计提供有益的参考。Because of its changeable posture,special-shaped arch bridges are widely used in the construction of urban landscape bridges.The landscape bridge across Lingang Avenue adopts the transverse asymmetric and longitudinal skew arch type,with a main span of 130 m.The main beam is a split double box arc beam,and the middle is connected by a cross beam.This paper comprehensively introduces its structural design,construction control and calculation analysis,summarizes the structural characteristics and mechanical characteristics of this kind of bridge,and puts forward the methods to improve its mechanical performance,which can provide a useful reference for the design of similar projects.
