Study on design of 1 000 dwt channel from Fuguo Port to Dongfeng Port in Tuhai River

In accordance with the relevant norms,combined with the characteristics of channel topography,geology,current and cargo composition of Tuhai River,firstly the design ship type was selected,and then the parameters such as tide-bound water level,channel depth and bottom elevation,channel width were determined based on the selected ship type.As for the changing direction of the channel,a long curved reach was designed according to theory of river bend radius,a sharp bend reach was designed using the way of channel turning radius in sea area.Finally,the waiting area was set up to solve the problem of waiting for tide and ships,and the pattern of double buoys mooring was adopted in the waiting area design.
