MIKE11模型在江宁区生态河综合整治工程中的应用

Application of MIKE11 Model in Comprehensive Improvement Engineering of Ecological Rivers in Jiangning District

摘要:

在生态河的综合整治工程设计中，利用MIKE11软件构建一维水动力模型，对生态河的排涝水位进行数值模拟，对比分析河道整治前后的最高排涝水位及高水位持续时间的变化情况，以评价在生态河综合整治工程中各比选措施对于提升河道排涝能力的实施效果。结果表明：MIKE11模型在圩区河道排涝水位模拟计算中具有良好的效果，可用于提高类似工程设计的可靠性和效率。模拟结果可为生态河的综合整治工程设计及日常运行调度管理提供一定的技术参考。

Abstract:

In the design of ecological river comprehensive improvement projects, the MIKE11 software is used to build the one-dimensional hydrodynamic model to numerically simulated the waterlogging drainage level of ecological river, and compare and analyze the changes of maximum waterlogging drainage level and the duration of high water level before and after river improvement in order to assess the implementation effect of various comparative measures for improving the waterlogging drainage capacity of river in the comprehensive improvement engineering of ecological rivers. The results show that the MIKE11 model had a good effect in simulating and calculating the waterlogging drainage level of river in polder areas, and can be used to improve the reliability and efficiency of similar engineering designs. The simulation results can provide some technical references for the design of comprehensive improvement engineering and the daily operation and scheduling management of ecological rivers.
