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。
對內河航道整治線寬度研究現狀進行瞭梳理,認為遲積河流“河相均衡”與輸沙平衡相一緻的基本原理,在現有研究中,隻有文獻[10]纔得以體現。該研究所得整治線寬度公式計算十分簡便,文章將其延伸于包括水庫變動迴水區在內的任何年內遲淤交替的河段;此外還提齣瞭樞紐下遊遲刷性河段整治線寬度確定方法。

In this study, literature on inland waterway regulation width was thoroughly reviewed. It is demon-strated that the fundamentals of the equilibrium sediment transport are in coincident with that of the equilibrium re-gime 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 and degrade within a year, including the fluctuating backwater reach. Moreover, this study has also presented a method to determine the regulation width in the scouring reach downstream dams.
