摘　　要：对内河航道整治线宽度研究现状进行了梳理,认为冲积河流"河相均衡"与输沙平衡相一致的基本原理,在现有研究中,只有文献[10]才得以体现。该研究所得整治线宽度公式计算十分简便,文章将其延伸于包括水库变动回水区在内的任何年内冲淤交替的河段;此外还提出了枢纽下游冲刷性河段整治线宽度确定方法。In this study, literature on inland waterway regulation width was thoroughly reviewed. It is demonstrated that the fundamentals of the equilibrium sediment transport are in coincident with that of the equilibrium regime relation in alluvial rivers. However, in the previous research, this point of view was only explicitly stated in the literature [10]. The present study has applied the simple equations for calculating the regulation width from litera- ture [10], and further extended its feasibility to all river reaches that alternatively aggrade year, including the fluctuating backwater reach. Moreover, this study has also presented a rn regulation width in the scouring reach downstream dams.
