一、问题的提出烟台港座落在北黄海南岸,芝环湾口处(如图1),属于正规半日潮港。烟台港港池水深较浅。根据水位历史资料记载及调查,从整理1972年至1979年上半年七年半资料看,最大风增水没有超过一米,风增水极值达到或超过80cm 的共2次;而风减水次数多,极值大,最大竟达到137cm,同时持续时间也长。从航运的角度来讲,减水的作用至关重要,随着四个现代化建设的发

First, the issue put forward Yantai port is located in the southern bank of the North Yellow Sea, the mouth of Chicago (Figure 1), is a formal semi-day tide port. Yantai port basin shallow water depth. According to historical records and surveys of water level, from the data of seven years and a half from 1972 to the first half of 1979, the maximum wind increased by no more than one meter, and the maximum of wind-induced water surge reached or exceeded 80cm in total. However, The number of times, the extreme value, the maximum actually reached 137cm, while the duration is also long. From the shipping point of view, the role of water reduction is of crucial importance. With the development of the four modernizations
