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.
