摘　　要：在弯曲通航河流上修建桥梁,其通航净宽对船舶安全航行及桥梁结构安全具有重要的影响。利用水槽模型试验成果,结合已有研究结论和有关标准及规范,提出了弯曲通航河道桥区通航净宽的计算方法,供航道和桥梁设计参考。After a bridge was built up in bend navigable waterway, it would exert great influence on vessels′ safe navigation and bridge structures. To ensure the safety of navigation and bridge, it is very important to calculate navigable bridge span. On the basis of model test result, and in combination with existing research conclusions and relevant standards and codes, this paper puts forward the calculation method of navigable bridge span on bend navigable waterway, which offers a reference for channel and bridge design.
