本文以上寨水库为研究对象,通过对水库水温结构的判定,分析分层水库坝前垂向水温与水深的关系,并结合主体工程设计采取的分层取水措施进行坝下水温的预测分析,进一步论证了分层取水能有效地减轻低温水对下游农田灌溉带来的不利影响,对同类型水库的坝前垂向及坝下水温预测分析提供了一定的借鉴意义.
本文以上寨水庫為研究對象,通過對水庫水溫結構的判定,分析分層水庫壩前垂嚮水溫與水深的關繫,併結閤主體工程設計採取的分層取水措施進行壩下水溫的預測分析,進一步論證瞭分層取水能有效地減輕低溫水對下遊農田灌溉帶來的不利影響,對同類型水庫的壩前垂嚮及壩下水溫預測分析提供瞭一定的藉鑒意義.

This article taking Shangzai Reservoir as the object of study,throughthe determination of water tem-perature in the reservoir,analyzed the relations between of vertical water temperature and water depth in front of the dam of thelayered reservoir;It carried out the water temperature forecast analysis in down dam combined with the main part of the project designed to take water from different levels,and further demonstrated that the stratified water can effectively reduce the adverse effects of low temperature water downstream on farmland ir-rigation;It provides a certain referential significance for the similar projects.
