| 摘 要： | 根据水利枢纽下游浅滩的碍航特性以及是否受到枢纽下泄水流的非均匀流影响,将碍航浅滩分为4种类型,分析了非恒定水流的输沙能力,讨论了碍航浅滩年内输沙不平衡的处理方法。在此基础上,提出了枢纽下游航道整治线宽度计算公式。该公式简化后与规范所推荐的公式一致,并采用汉江资料进行了计算。

| Abstract: | Based on the navigation obstruction characteristics of the lower reach and whether the non-uniform flow from hdro-junctions affects the shallow areas,navigation obstructions of lower reaches are divided into four types.The sediment load capacity of non-uniform flow is analyzed.The method of un-equilibrium annual sediment transport on lower reaches is discussed.On this basis,the calculation formula of the regulation width of waterways downstream of hydro-junctions is put forward.After simplification,the formula is consistent with the one recommended by the standard.Data from the Hanjiang River is used with the formula to calculate the regulated width. |

| Keywords: | downstream of hydro-junction classification of navigation obstruction of lower reach regulated width of waterway |
