In order to achieve the goal of highly efficient navigation,it is necessary to analyze the relationship among the number of sluice dams,navigation efficiency and project investment in channelized rivers that have not considered navigation needs,and the cascade layout scheme should be reasonably determined.Taking the channelized Gongcheng River as an example,this paper systematically summarizes the main influencing factors and layout principles of the navigation hydro-junction layout,puts forward three feasible cascade layout schemes on the basis of analysis and demonstration,analyzes the factors influencing navigation efficiency and project investment,and obtains the result that the navigation of Gongcheng river should adopt the three cascade channelization scheme.The conclusion is that channelization projects with navigation development as the main task should prioritize navigation efficiency,set reasonable distance between cascades,and control the number of cascades.The principles,research ideas and methods of the layout of navigation hydro-junction have positive reference significance for the planning and construction of similar projects and the revision of codes.
