上寨水库坝前垂向与坝下水温预测分析

The analysis of the forecast of water temperature in upper dam and down dam of Shangzhai reservoir

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。

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.
