长江口北港航道开发条件评价及开发时序探讨

合理开发北港航道可缓解目前长江口主航道在南港段面临的巨大通航压力、畅通长江黄金水道、拓宽上海港在长江口的岸线利用范围。通过分析北港航道的开发条件,对北港航道的可开发规模及开发时序作出探讨。分析认为:现阶段可通过规范北港通航,利用自然水深建设5 000吨级航道,部分缓解南港的通航压力;近期可开辟8 m航道,通航2万吨级及以下船舶;中远期则需全面整治北港,开辟10 m航道,满足3万吨级船舶的通航需求。

Development conditions and schedule of north channel at Yangtze estuary

Proper development of the north channel will reduce the navigation pressure of the south channel, smooth the Yangtze waterway, and broaden the coastline application at the Yangtze estuary. By analyzing the development conditions of the north channel, we research the development scale and schedule of it. It is concluded that at the present stage, we may regulate the north channel and construct a 5 000 DWT channel with the natural water depth so as to reduce partially the navigation pressure; In the near future, we can develop the 8m-deep-water channel and realize navigation of 20 000 DWT ships; As for the mid & long term, we shall regulate the north channel comprehensively and develop a 10 m-deep channel to satisfy the navigation of 30 000 DWT ships.
