摘要
本文针对超宽曲线连续箱梁内外侧支反力的不均匀性,以桥墩受力的合理性为原则,提出结合梁格法和实体元法对支点合理布置形式进行定性计算的简易方法。经实际工程验证,该方法为优化超宽曲线连续箱梁桥墩受力提供有力保障,且因计算量小不影响设计工期,为同类桥梁方案设计提供参考。
Based on the inhomogeneity of super-wide curved concrete box-beam＇s supports, we proposed a simple qualitative calculation method for reasonable support layout using grillage method combined with solid element method.This method provided an optimization of super-wide curved concrete box-beam＇s force status.
