| 摘 要： | 采用宽度平均立面二维水动力模型CE QUAL W2，对紫坪铺水库水温结构进行了数值模拟，运用库区实测资料进行了模型的参数率定及验证。库区及下泄水温的计算值与实测值吻合良好，显示模型能较好地模拟库区垂向水温分层的形成发展过程，以及升温期电站下泄水温变化，证实该模型对紫坪铺水库的水温模拟是适用的，也可为同类型水库提供参考。经参数灵敏度分析，发现水温模拟对模型中的风遮蔽系数与动态光遮蔽系数最为敏感，其余参数影响不明显，可取模型默认值。其中风遮蔽系数增大，风速加大，水库表层温度降低，水库垂向混合作用增强，温跃层下移，水温分层明显减弱，库底水温明显提升；动态光遮蔽系数增大，入射的太阳辐射增强，水库上层40 m水体温度升高，中下层水体温度无明显变化

| Abstract: | CE-QUAL-W2,a two-dimensional,laterally averaged,hydrodynamic model,was applied to simulate the water temperature structure in Zipingpu reservoir.Model parameters were adjusted during calibration and the simulation results were compared with the observed measurements in site.The simulation results of area of reservoir and effluent flow were compared favorably with the observed measurements,showing that the model can simulate the process of formation and development in vertically stratified reservoir and chan... |
