一、前言镇海港位于甬江河口。自1975年建成以后,由于港池、航道回淤速度快,使已建成的港口未能投入生产。为改善航道和港池水深,各单位曾做了大量的分析研究工作,提供了很多有价值的资料。1979年7月,我们根据几年来的分析研究,提出了改善航道与港池水深的三项整治措施:即拆除煤码头上游的水尺码头,在南岸金鸡山脚下建立挑流丁坝以及在大游山以东修筑北导流堤。前二项工程,尤其是煤码头对岸挑流丁坝建成后,使码头前沿一度出现了

Since its completion in 1975, due to the dams in the harbor, siltation of the waterway is fast, so that the completed ports can not be put into production. In order to improve the waterway and the depth of the basin, all units have done a great deal of analytical work and provided a lot of valuable information. In July 1979, based on several years of analysis and research, we proposed three measures to improve the waterway and the depth of the port basin: to demolish the water terminal at the upstream of the coal terminal, to build a dikes barrage at the foot of Jinji Mountain in the south bank, Building east of the mountain to the north of the dike. After the completion of the first two projects, especially the construction of the Dikes along the bank of the coal terminal, the front of the terminal appeared once
