【摘要】 远距离引水工程中,一般在线路上要设计一些小型调节水库,当水库地处内陆深处时,冬季气候寒冷,库水结冰将影响引水工程系统的正常工作。本文针对引黄入晋工程中的申同嘴水库,对水库水温变化情况进行了计算分析,得出维护冬季水库引水安全的主要措施为:①尽量保持水库高水位;②若万家寨水利枢纽取水口处水温低于1.5℃,可采取加大水体流量的方法防止结冰。更多还原

【Abstract】 Generally design some minor regulative reservoirs at long-distance water transfer project. As it located in interior of land ,water in the reservoir will be frozen for the influence of abominable climate in the winter. Temperature analysis for water in reservoir are done according to the Shentongzhui Reservoir of Wanjiazhai Yin Huang Ru Jin Project .Calculating results show that① Keep the high water level of reservoir as far as possible. ② If temperature of water is no more than 1.5 ℃s at intake of Wanjiazhai hinge , increase discharge quantity to avoid water frozen.更多还原
