摘　　要：分层型水库垂向水温计算常采用垂向水温分布模型的数值解法或经验公式法,数值解法计算工作量较大,经验公式法简便但不能随便移植使用。在Huber和Harleman建立的垂向一维水库水温模型的基础上,简化模型结构和部分参数,推导出垂向一维水库水温分布模型解析解,并用二滩水库的实测水温资料验证了解析解,得到了较好的效果。提出的垂向一维水库水温分布模型解析解法可用于深水型水库垂向水温分布预测。The numerical solution method or empirical formula of vertical temperature distribution model is often adopted in the calculation of vertical temperature for thermal stratification reservoir.However,the numerical solution method needs a large amount of calculation;the empirical formula is simple but can not be transplanted in all situations.Based on the 1D vertical water temperature distribution model established by Huber and Harleman,we simplify the model structure and partial parameters and deduce the analytical solution of the model.Besides,the analytical solution is tested and verified by the measured data of Ertan Reservoir.The analytical solution of l D vertical temperature distribution model can be used for the vertical temperature distribution prediction in deep-water reservoir.
