基于MIKE21FM的黄壁庄水库水动力模拟研究
|
摘要
黄壁庄水库是具有控制性作用的大(一)型水利枢纽工程,确保其稳定性的水位、优良的水质等显得尤为重要。借鉴前人研究经验,采用MIKE21FM数值模拟软件,对黄壁庄水库"7·19"洪水期建立二维河网水动力模型进行数值模拟研究。经多次参数率定,结果表明MIKE21FM模型可以真实、有效反映黄壁庄水库水位、水流场变化过程,模拟精度满足计算要求。鉴于此模拟研究,可为水库水文预报、水库群联合调度提供可靠依据及技术支撑,具有一定的应用价值。
Huangbizhuang reservoir is a significant large water conservancy project to ensure the stability of the water level and high quality water. Based on the previous studies, this paper used MIKE21 FM to establish two-dimensional river network hydrodynamic model for numerical simulation research during " 7. 19" flood period in Huangbizhuang Reservoir. After many times parameter calibration, the results showed that the changing process of water level and water flow could be reflected factually and efficiently by MIKE21 FM and its accuracy would meet the calculation requirement. In view of the simulation study, it provided reliable basis and technical support for hydrological forecast and joint operation of reservoirswhich must havea certain application values.
