摘　　要：弯梁桥经济适用性强,但弯扭耦合作用导致桥梁结构受力较复杂,对某立交4-20 m钢筋混凝土弯箱梁桥进行计算、分析,总结该类桥型的设计要点,有针对性的提出一些解决方案,希望为同类型桥梁的设计提供一些参考借鉴。The curved girder bridge has strong economic applicability,but the coupling action of bending and torsion leads to the complexity of the bridge structure.In this paper,the calculation and analysis of a 4-20 m reinforced concrete curved box girder bridge overpass are carried out,and the design key points of this type of bridge are summarized,put forward some targeted solutions,hoping to provide some references for the design of the same type of bridge.
