摘要
为研究水网连通工程对大东湖水动力条件的影响范围和程度,建立了大东湖水动力模型,并对模型进行了率定和验证,对比分析水网连通前后流场的变化,阐述实施大东湖调度方案对大东湖各子湖泊水动力条件的影响。结果表明,调水后大东湖水流加快,与原处于封闭情况下的风生流场有很大区别,在考虑风生流场情况下水网连通工程实施后大东湖水系流速大于0.01m/s的水面面积比连通前扩大了一倍以上,为大东湖生态水网工程的运行调度提供了参考。
To study the influence of water network connection project on hydrodynamic conditions in East Lake,a hydrodynamic model was built in this research.The model is verified and calibrated.The dynamic characteristics of flow field before and after water network connected are analyzed,and the changes of each sub-lake are also discussed under different dispatching conditions.The results show that the water flow of East Lake quickened after water transfer.There is great difference of wind-induced flow field.The water area of East Lake water system,that water velocity is greater than0.01m/s,is twice times than before under condition of wind-induced flow filed.So,it provides reference for operation of ecological water-network project in East Lake.
