摘要
由于万家寨水库蓄水 ,库区河道由不封河转为稳定封冻河段 ,回水末端到拐上河段受冰花、冰块阻水影响水位壅高 ,交通水泥厂断面最高壅水 6 5m ,超过水库设计回水淹没线。作者在现场观察基础上 ,结合万家寨水库实测冰情资料 ,对万家寨水库封、开河情况进行了介绍 ,就流量、流冰密度、库水位及地形等因素对封。
Due to storing water of Wanjiazhai Reservoir, the river channel in the reservoir region transits from no freeze_up into freeze_up. Affected by frazil ice and ice cake jam flow, the ice jam stage rises in the reach from the upstream end of backwater to Guaishang. The ice jam stage rises by 6 5m high at the section of the traffic cement mill, which exceeds the reservoir design backwater elevation. Based on the field observation and the measured data, the paper introduced the basic information of the freeze_up and thawing in the reservoir. Finally, the effect of flow discharge, ice discharge, reservoir operational water level and channel geomorphy on the freeze_up, thawing, and water stage rising is analyzed.
