回顾了小浪底水利枢纽工程初步设计以来水库减淤运用的研究情况 ,总结以往的经验 ,结合当前的实际 ,对水库减淤作用、水库运用方式与分阶段运用、主汛期调水及运用方式的动态研究等问题提出了一些新的认识。分析论证了调水调沙与拦粗排细、近期调度与长远分析、小浪底工程与其他治黄工程建设等问题的辩证关系。提出水库初期运用应以调水为主 ,其后逐步抬高运用应与适时降低水位冲刷相结合。要及时总结经验 ,不断跟踪研究 ,及时合理调整运用方案。
Reviewing the research on reservoir siltation and application since the preliminary design of Xiaolangdi Multipurpose Dam Project, summarizing the past experiences and combining with the current practice, this paper analyzes the dynamic characteristics of reservoir silt reduction, reservoir operation and phased application, water diversion and application modes in main flood season Research and other issues put forward some new understanding. The dialectical relationship between water diversion, sediment regulation, recent scheduling and long-term analysis, construction of Xiaolangdi Project and other Yellow River project construction was analyzed and demonstrated. It is suggested that the initial operation of reservoirs should be mainly water diversion, and then the application of gradual elevation should be combined with the timely reduction of water level erosion. To summarize the experience in a timely manner, keep track of research, timely and reasonable adjustment program.
