《南水北调与水利科技》：南水北调东线南四湖出、入湖泵站开启时间差分析研究（武周虎,罗辉,刘长余,孙丽凤,赵培青）（摘要）

摘要：针对南水北调东线南四湖上、下级湖调水的出、入湖口提水泵站开启时间差计算确定问题，开展了调水出湖泵站开启的充要条件、开启时间和湖内水位升高速率等相关内容的研究。其成果表明出湖泵站开启在保证泵站引水渠进口水位下降控制不低于相应设计水位的充要条件是：入湖口提水泵站输水惯性波前锋到达出湖口，且入湖调蓄水量能满足输水流量形成恒定流水面线比降的楔形水体容积。同时，研究提出了出湖泵站开启时间、湖内水位升高速率和湖水位的计算公式以及相关图表，为工程设计和未来的调度运行管理奠定了理论基础。

Abstract:By calculating start-up time difference of in-lake and out-lake pumping station in the upper and lower lakes,the article studies the necessary and sufficient conditions of start-up out-lake pumping station,the relationship between the start-up time of out-lake pumping station and rising velocity of lake water level.The necessary and sufficient conditions are the start-up of the out-lake pumping station does not cause the out-lake pumping station diversion channel import level to fall below the corresponding water level of the control and design conditions.The related conditions are the water begins to rise when the in-lake inertial wave reaches the lake exports;the water-holding capacity of the lake satisfies the water distribution current capacity to form the wedge-shaped water cubage of constant running water surface profile gradient,formula and tabulations of the pumping station start-up time.Rising velocity of the water level and lake water level for engineering design are also provided.

Key words:Nansi Lake;pumping station;start-up condition;start-up time;rising velocity of the water level
