Guangzhou Port Main Channel Optimize Research

Port system is a complicated system.Channel is an important part of the port system,it's a base element of the port transportation.The characteristics of the Guangzhou port main channel is: long and narrow,the natural depth of the water is limit,many way points,heavy traffic density.Because of the characteristics of the Guangzhou port main channel,upgrade need a lot of money and long time,it's easy to cause the channel's construction fall behind the economy development,the channel transit capacity can't meet the requirement of the port develop.Because of the port development,the channel transit capacity and the port requirement is unmatched.The first: owing to the increase of the port handling capacity,more and more vessel to port,the traffic in the channel become crowd.Fore and aft the high tide,many large vessels one by one in queue sailing in port.There is many elements to affect the speed of the vessel sailing in Guangzhou port main channel,it's easy to cause a traffic congestion.The second : the vessel to port become larger,in case the vessel exceed a class of tonnage,the vessel forbid meeting end on in the channel,the VTS must carry out traffic control,let the large vessel one-way sailing in the channel,other vessel can't join in the channel except the vessel in the same direction.It's serious affect the channel navigation efficiency.The transit capacity of the Guangzhou main channel can't meet the requirement of the port development need to solved urgency.The paper through analyze the port handling capacity and the type of vessel to Guangzhou port,calculate the ability of the main channel through cargo and through vessel respectively.Analyze the economy of the central region of the Guangzhou port,estimate the port handling capacity of Guangzhou port in the future,and calculate the accordant channel transit capacity at that time.Analyze the tape of vessel to port,and forecast the tape of large vessel to port,calculate the channel transit capacity what able two large vessel meeting end on in the channel.Compare the two channel transit capacity of the channel,the one which can meet the requirement of both sides is the optimize plan.
