摘　　要：大水位差山区河流中常规"一"字形布置的斜坡客运码头存在水域工程量较大、投资较高,对河道行洪和通航安全造成不利影响。提出一种由主斜坡道和副斜坡道组合的斜坡客运码头梳式布置,实现了大水位差山区河流中船舶的分级分段靠泊,解决了常规布置斜坡客运码头在高陡地形的狭窄河流中存在的一系列局限性问题。通过与常规斜坡客运码头进行对比分析,梳式布置对山区河流地形特征的适应性更强,能有效减小船舶靠泊作业时对水域的占用、降低施工难度、节省工程投资。Normal line-type arranged sloping wharf for passenger transport in mountain river has huger engineering amount of water area and higher investment,and has adverse influence on river channel flood and navigation safety.We propose a comb-type sloping passenger wharf combination arrangement by main ramp and assistant ramp,realize that ships berthing grade and sublevel in mountain river of great water level difference,and solve a series of limitations that sloping passenger wharf arranged normally in high steep terrain and narrow river.Through comparative analyzing with normal sloping passenger wharf,comb-type sloping passenger wharf has stronger adaptability in terrain feature of mountain river,also can effectively reduce occupancy of water area when ships berthing and construct difficulty,and save project investment.
