平直海岸填筑式港口布置水流条件研究

以绥中新港码头方案论证为例，针对平直海岸的水流特点，通过平面二维潮流数学模型对填筑式的突堤码头实施后的水流进行模拟计算，从港池、航道平面流态、码头和航道横流及工程建设对周边水域的影响等角度对码头工程实施的水流条件进行分析。分析认为，平直海岸码头前沿不宜突出岸线太多，相邻港池口门宜尽量布置在同一水平线上以避免口门附近出现复杂流态和减少相互影响；应尽量采用栈桥码头布置较大吨位泊位，可以减小围填工程对周边水流的影响。

Flow conditions of filling-type port on rectilinear shoreline

Taking the demonstration program of Suizhong Xingang as a study case, we use a 2D numerical model for straight coast to simulate the current field of the filling-type jetty port, and discuss the factors such as plane flow pattern, cross-flow of port and channel, and the impact of construction to surrounding water. The results suggest that the wharf apron is not advisable to protrude too much, the entrance ought to be arranged in the same level as far as possible to avoid complex flow near the entrance and reduce the interaction between them, and large tonnage wharf would be best to be laid in the trestle form to decrease the impact on the surrounding water.
