烟台港芝罘湾港区北防波堤改建工程方案

Reconstruction project schemes on north breakwater of Zhifu Port area in Yantai Harbor

针对烟台港芝罘湾港区现有北防波堤侵占三突堤南侧岸线问题,提出3个改建方案,采用数值模拟的方法,推算不同方案下港池内测点波高。计算结果表明,拆除现有防波堤后,即使规划三突堤建成,因缺少原北防波堤的掩护,对ENE和E向入射的波浪,整个港池码头前沿的波高明显增大;新建防波堤对港内水域有较好的掩护作用,港内测点波高分布情况总体上好于港区现状,其中以新建突堤式防波堤方案掩护效果更优。

In view that the existing north breakwater occupies coastline in the south of No.3 jetty of Zhifu Port area in Yantai Harbor,three reconstruction project schemes are proposed,and the numerical simulation method is used to calculate the wave height of the inner test point in the harbor basin.The results show that,after dismantling the existing breakwater,even if the No.3 jetty was completed,the wave height of the ENE and E to the incident waves and the port front of the whole port was obviously increased because of the lack of the shield of the original north breakwater.The newly-built breakwater has a better shielding effect on the waters of the port,and the distribution of the wave height in the inner test point of the port is generally better than the present situation,among them the scheme of jetty breakwater is more superior.
