摘要
在滨州港海域水沙环境分析的基础上,采用数学模型对滨州港规划方案水动力变化、泥沙淤积等进行研究,分析滨州港规划方案对黄骅港海洋动力和泥沙环境的影响。研究结果表明:规划方案的实施未改变大范围海域潮流运动规律,外海涨落潮潮流主向仍为东西向,至近岸转为与等深线基本垂直;滨州港规划方案使得黄骅港外航道内和以北、以及黄骅港和滨州港两港之间区域,涨、落潮时段潮流矢量普遍发生逆时针偏转,潮流向与黄骅港航道轴线方向夹角减小,涨、落急时刻黄骅港航道流速变化很小,对航道基本没有影响;工程后,该海域的波浪场仅在滨州港港岛周围发生了变化,对黄骅港航道及其周围的波浪场没有影响;滨州港规划方案引起滨州港港岛周围含沙量场发生变化,对黄骅港航道含沙量场没有产生影响;黄骅港、滨州港海区泥沙的净输移方向应该是由南向北、由近岸向外海输移方向,滨州港的规划方案遏制了部分泥沙来源,对减少黄骅港外航道泥沙淤积有利。综合分析认为:滨州港规划方案对黄骅港海洋动力和泥沙环境无不利影响。
Based on the analysis of the water and sediment environment of Binzhou Port, the hydrodynamic change and sediment deposition of Binzhou Port planning scheme were studied by using mathematical model method, and the influence of Binzhou Port planning scheme on the dynamics and sediment environment of Huanghua Port was analyzed. The results show that: the implementation of the planning scheme has not changed the law of tidal current movement in a large area of the sea. The main direction of the offshore tidal current is still east-west, and it turns to be perpendicular to the isobath line;The planning scheme of Binzhou Port makes the tide vector generally turn counterclockwise during the period of flood and ebb tide within and to the north of the outer waterway of Huanghua Port, as well as the area between Huanghua Port and Binzhou Port, and the angle between tide direction and the waterway axis direction of Huanghua Port decreases, the velocity of Huanghua Port changes little and has no influence on the channel basically;After the project, the wave field of this sea area only change around Binzhou Port and island, but had no influence on the wave field of Huanghua Port and its surrounding channel;The planning scheme of Binzhou Port causes changes in the suspended sediment concentration field around the Binzhou Port, but has no adverse effect on the suspended sediment concentration field of the channel of Huanghua Port;The net sediment transport in the sea area of Huanghua Port and Binzhou Port should be along the direction from south to north and from coastal to offshore. The planning scheme of Binzhou Port partly contained the sediment source, which was beneficial to reduce the sediment deposition in the channel outside Huanghua Port. Comprehensive analysis shows that Binzhou Port planning scheme has no adverse effect on dynamics and sediment environment of Huanghua Port.
