海门港外航道通航条件研究

Research on Navigation Condition in Outer Channel of Haimen Port

海门港外航道水深浅（最浅处达１．２ｍ）且距离长，吃水深的重载货轮都须乘潮进港。本文针对海门港验潮井的历史演变，考证了近年来海门港航道的稳定性，同时指出当前外航道参照潮汐预报点的数据代表性不佳，提出在外航道“白沙”设一潮汐预报点供重载船舶乘潮作业参照，为海门港外航道通航提供新的航海保证条件。

The outer channel of Haimen Port is very shallow and lengthy. The shallowest water is only 1.2m from the water surface. Deep-drafted cargo ships with a heavy load have to enter the port when the tide is flowing. This essay is mainly about the historical change of the tide-measuring well in Haimen Port and prove the stability of the channel of Haimen Port in recent years. At the same time the author mentioned that they lack typical reference data of tide forecast and it's necessary to set up a tide forecast spot in Baisha on the outer channel for the reference of heavyloaded cargo vessels so as to creat a new condition to ensure the safe navigation in the outer channel of Haimen Port.
