潮汐河段码头对水流影响的数值模拟分析

摘要

The characteristics of the flow in the segments of tidal river is complex,in order to analyze the im-pact of the dock construction in the tidal rivers on the flow,a two-dimensional mathematical model for the nu-merical simulation wasestablished.The Results show that:pier most obviously impact on the water flowat up anxious and off the anxious moments and has a similar law,but in the opposite direction.%　　潮汐河段水流特性复杂，为了分析潮汐河段码头建设对水流影响，建立二维数学模型进行数值模拟计算。结果表明：涨急和落急时刻码头对水流的影响最为明显，具有相似的规律，但方向相反。
