摘　　要：对于受地形、地表及地下构筑物限制的城市桥梁,曲线钢箱梁因交通影响小且施工工期较短而成为首选。曲线钢箱梁受力复杂,与直线桥梁相比更具设计难度,一旦设计不合理,将会对后续使用产生一系列后果。本文通过分析曲线钢箱梁的受力特征、常见病害及成因,结合某小半径曲线钢箱梁的实际设计案例,对其设计要点进行探讨,以期为同类型曲线钢箱梁的设计提供借鉴和参考。Restricted by terrain,surface and underground structures,curved steel box girder has become the first choice because of small impact on traffic and short construction period.Under complicated stresses,the design of curved steel box girder is more difficult than that of straight bridge.If the design is unreasonable,it will bring a series of consequences to the subsequent use.By analyzing the stress characteristics,common diseases and causes of the curved steel box girder,and combining with a practical design case of a small radius curved steel box girder,this paper discusses the key points in design,so as to provide a reference for the design of the same type of curved steel box girder.
