在水工建筑物设计中有时需要对建库后坝前不同水深可能出现的温度及其变化规律有个预先的估计。如在确定整体式混凝土坝的接缝灌浆温度与计算坝体温度应力时,需要预测坝前各层水的多年平均水温、年变幅;在设置水电站厂房空调的取水口高程时,需要预测坝前各层水的8月份水温(在我国8月份的气温和库水温一般均较高,故空调用该月的水温来控
In the design of hydraulic structures, it is sometimes necessary to have a prior estimate of the possible temperature and its variation at different depths after dam construction. For example, in determining the joint grouting temperature of monolithic concrete dam and calculating the temperature stress of dam body, it is necessary to predict the annual mean temperature and annual amplitude of water in all layers of the dam; when it is necessary to set the water intake elevation of the air conditioning plant in a hydropower station, August before the water temperature of all layers of water (in China in August the temperature and the reservoir water temperature are generally higher, so air conditioning with the month’s temperature to control
