| 摘 要： | 根据汛期特殊运用年份的水库运用情况，通过实际观测资料，与来水条件相似的正常运用年份对比分析潼关以下库区冲淤变化以及潼关高程升降的基本规律，对比分析可知：平水期适当抬高水位运用，不对潼关以下库区及潼关高程的自然冲刷状态产生不利影响；在洪水期水量沙量集中时，应尽量降低水位（295－298m)排沙运用，增加峰前比降，加大洪水冲刷力度，排沙效果会更好。

| Abstract: | According to operation condition of the reservoir in flood season of especial years and observed data, the basic law of erosion and deposition changes in reservoir region below Tongguan and raising lowering of Tongguan elevation is analyzed in comparison with similar normal year. It can be known from the analysis that as the water level is heightened suitably in the period with normal base flow, an unfavorable effect could not cause in reservoir region below Tongguan and under the natural erosion condition of Tongguan elevation. When incoming water and sediment are concentrated in flood season, the water level should be lowered for discharging sediment, the water surface slope before flood peak increased and flood scouring enlarged, the effect of discharging sediment can be better. |
