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。
In order to study the scope and extent of water network connection project’s influence on hydrodynamic conditions of Dadong Lake, the Dadong Lake hydrodynamic model was established and the model was calibrated and validated. The changes of the flow field before and after water network connection were compared and analyzed. Influence of East Lake Regulation Scheme on Hydrodynamic Conditions of Lakes in Dadonghu Lake. The results show that the flow of Dadong Lake after water diversion is accelerated, which is quite different from the wind flow field where the original Dongtu Lake was closed. When the wind-induced flow field is considered, the Dadong Lake water flow rate is more than 0.01m / s The area of water surface more than doubled before the connection, which provided a reference for the operation and regulation of Dadong Lake Ecological Water Network.
