在控制河南河段滩岸坍塌、河势变化及整治工程险情的前提下 ,从有利于下游尤其是山东河段的减淤出发 ,论证了小浪底水库 2 0 0 0年减淤调度运用的关键调控指标 ,推荐起始运行水位采用 2 0 5m ,调控上限流量采用 2 60 0m3 /s ,调控库容采用 8亿m3 。分析了 2 0 0 0年遇不同水沙条件时库区淤积变幅及下游河道清水冲刷风险。
On the premise of controlling the danger of bank collapse, river regime change and remediation project in Henan reach, from the point of view of reducing siltation in the lower reaches, especially in Shandong reach, the key regulation and control of the Xiaolangdi Reservoir dredging deployment was verified Indicators, the recommended initial operating level with 205m, regulating the upper limit of flow using 2 60m3 / s, regulating storage capacity of 800000000 m3. This paper analyzes the siltation fluctuation in the reservoir area and the risk of fresh water scouring in the lower reaches of the river in different water and sediment conditions in 2000.
