调水工程中小型水库的冬季水温分析——申同嘴水库水体结冰及温度计算

Temperature analysis for minor reservoir in water transfer project

当调水工程地处内陆深处时 ,由于冬季寒冷 ,其中小型调节水库的水体可能会结冰。本文根据库水水温的时、空分布方程 ,对申同嘴水库进行了结冰及水温分析研究 ,计算了库水的整体结冰时间和水体出库温度。结果表明 :1库水结冰时间决定于水库的水位和初始水温 ;2对出库水温起主要影响的是入库水体的流量 ;3入库水温低于 2 .0℃ ,流量低于 12 .90

As winter's temperature is low, the water in minor reservoir can freeze while water transfer project is in inland. Study about freezing condition and water temperature is done according to time and space distribution equation. Computation results of Shentongzui reservoir show that:①freezing time is determined by its water level and starting temperature; ②outside temperature of water is effected by discharge quantity; ③that inside temperature of water is below 2.0℃ and discharge quantity is below 12.9m 3/s are at the risk of freezing.
