摘　　要：对3种常见跨径布置的小半径曲线钢筋混凝土连续箱梁,在不同曲线半径下的内外侧支座反力分布进行计算分析。通过相应调整支座反力,对曲线钢筋混凝土连续箱梁内外侧支座反力的分布规律进行总结,得出的结论可供此类设计参考。Taking three kinds of small radius curve RC continuous box girder bridges with normal span layouts for example, calculation analysis is made about the distribution of inner and outer support reaction force under different curve radius. The related distribution rule is summarized by adjusting the support reaction force correspondingly and the conclusion is hoped to be some references for similar designs.
