摘　　要：　本文建立了计入浮力影响的立面二维水温模型,用二滩的实测资料对模型进行了验证,再将该模型应用于另一待建的河道式深水库,精细地模拟出斜温层的形成、发展和消失,分析了水库全年的温度分层结构。In this study the laterally averaged two-dimensional k-ε turbulent model is firstly tested in Ertan reservoir and the results are compared favorably with the observed measurements in site. Then it is applied to predict the thermal stratification for another reservoir. The formation, growth and erosion of the thermocline are simulated and the development of the thermal structure is analyzed all-around.
