| 摘 要： | 研究三峡水库汛期水位控制运用方案,对于充分发挥三峡水库的综合效益具有重要意义.本文在分析三峡水库洪水季节性变化规律的基础上,综合多种分期方法的结果得出三峡水库汛期分期方案,并按照规范推求分期设计洪水.根据不同分期的来水情况分别拟定防洪调度规则,在确保防洪安全的前提下,利用分期设计洪水调洪演算确定汛前期和汛末期汛限水位,采用预报预泄方法确定主汛期水库水位控制运用方案.历史资料和随机生成的长径流系列调洪演算结果表明:所拟定的三峡水库汛期水位控制运用方案安全可靠、合理可行,可显著地提高三峡水库的兴利效益.

| Abstract: | Storage level control during flood seasons is important to the operation and benefits of the Three Gorges reservoir(TGR). This paper analyzes the seasonal variation of reservoir inflow hydrographs,combines several multi-stage methods,and finally obtains a synthetic scheme of TGR storage level control. The scheme is obtained by three steps,adopt a different flood operation rule for each flood stage,determine the storage level limits before and after flood time by flood routing calculation to satisfy the safe... |
