摘　　要：大规模的海洋工程建设会对周边海域的水动力产生不同程度的改变,基于MIKE21Flow Model FM模型研究了张家埠新港建设对附近海域水动力环境的影响。结果表明:新港建设对潮位的影响很小,仅仅局限在工程附近的有限区域;工程建设对附近海域流场有一定的影响,工程东西两侧海域流速减小、南侧海域流速增大,流速变化在-0.55～0.24m/s之间,流向变化在-10°～50°之间,在距离工程4 000m外影响程度较小。Large-scale marine construction will affect the hydrodynamics in the adjacent waters. The impact of new port construction in Zhangjiabu on hydrodynamic environ- ment in the waters adjacent to engineering construction was studied by using the two-di- mensional depth-integrated hydrodynamic model-MIKE21 Flow Model. The results show that the construction of the new port will have little impact on the tide level, but this is restricted only to a limited area adjacent to the engineering. In the studied area the current field will be influenced to a certain extent, with the velocity of tide current decreasing in the waters to the east and west of the engineering construction and increas- ing in the area to the south of the construction. The current velocity will change in a range between -0.55 m/s and 0.24 m/s and the current direction varies between -10° and 50°. In the waters about 4 000 m away from the construction the impact on the tidal current will be to a small extent.
