摘要
根据三门峡水库长期运行情况及库区实测水沙资料,分析了潼关高程变化的影响因素,对降低潼关高程的措施进行了研究。汛期不完全畅泄、低水位运行时间短、汛期控制水位发电、汛末过早蓄水、非汛期运用水位高是潼关高程抬高的主要原因。20世纪90年代以来的枯水系列加重了潼关高程的抬高。改变水库运用方式是降低潼关高程的最重要措施,水土保持措施、河道整治工程、潼关河段清淤工程等对降低潼关高程具有积极作用。
The long-term measured data of Sanmenxia Reservoir are analysed to enable consideration of the causes of water levels at Tongguan station. Measures to reduce flood heights are also analyzed. The main causes of rising water levels at Tongguan station are limited flow in the reservoir in flood season and high (water) levels in front of the dam in the dry season. To change the operational mode of Sanmenxia Reservoir is the most effective measure to reducing flood heights at Tongguan.
