人工湖湖底形态优化数值模拟分析

Numerical Simulation and Analysis on Morphology Optimization of Artificial Lake Bottom

为了合理确定人工景观湖湖底形态,采用丹麦水利研究所开发的Mike Flood一维二维耦合模型,以及Mike 3三维水动力模型对湖底形态进行研究,得到不同湖底形态对于水流动力的影响。结果显示,弧形深槽的湖底形态下湖区流场更加均匀,低流速的水流区域范围更小。

In order to reasonably determine the lake bottom morphology of artificial landscape lake,the Mike Flood one-dimensional and two-dimensional coupled model developed by Danish Institute of Water Resources and Mike 3 three-dimensional hydrodynamic model are used to study the lake bottom morphology.The influences of the different lake bottom morphologies on the hydrodynamic force are obtained.The results show that the flow field of the lake area under the arc-shaped deep-trough lakebed morphology is more uniform,and the area of water with low velocity is smaller.
