摘    要:运用建立的株洲枢纽至长沙枢纽间长河段二维水流数学模型,研究了长沙枢纽库区水面线变化特征,分析了水库调度对库区通航水深条件的影响。依据设计确定长沙枢纽水库淹没范围控制方案,计算出水库淹没曲线控制线,推求了库区控制断面处(湘潭水文站)不增加水库淹没损失的坝前蓄水位与坝址流量关系,合理确定长沙枢纽预泄的动态控制水位调度线,为后续水库优化调度提供边界约束条件。

关 键 词:水库  淹没曲线  数学模型  长沙枢纽

Abstract:Using the two-dimension mathematical model of long river section between Zhuzhou and Xiangjiang hydro-junctions,the paper studied the variation feature of water surface curves in the area of Changsha hydro-junction and analyzed the influence of reservoir operation on navigation water depth in reservoir area.According to the design scheme, it determined the control scheme of submerged scope in the reservoir area of Changsha hydro-junction,and calculated the reservoir control line of submerged curve,and derived the relation between storage water level and flow of reservoir controlling section (Xiangtan hydrological station) and reasonally determined the pre-discharge water level scheduling line so as to offer the boundary constraint conditions for the subsequent reservoir optimization operation.
Keywords:reservoir   submerged curve   mathematical model   Changsha hydro-junction
