摘　　要：在总结现有整治线宽度计算研究成果的基础上,根据汉江来水来沙条件和整治河床演变特点,基于河流输沙平衡及能量耗散原理,建立了适应于汉江下游悬移质造床为主河段的整治线宽度新的计算方法,该方法应用于汉江下游航道整治工程中,航行条件获得了显著改善.该研究成果为未来航道整治工程规划设计提供了重要参考.Based on a review of the current research on the calculation of the width of regulation lines,a new method taking into account the water flow and sedimentation condition,as well as the evolution of the regulated river bed was proposed.The method was based on the theory of sediment transport balance and energy dissipation in river channel,and well suited to the suspended sediment transport characteristics of the lower reaches of the Hanjiang River.When applied to the waterway regulation engineering in the lower reaches of Hanjiang River,the navigation conditions were greatly improved.The results can provide an important reference for future waterway regulation project planning.
