陆浑灌区渠首闸分水计算方法研究

Study on Water Diversion Calculation Method of Headgate in Luhun Irrigation Area

陆浑灌区为豫西地区唯一省管大型灌区,灌区渠道的定标定量输水工作,事关渠系工程安全和供水安全。灌区渠首闸具有节制流量和配合泄洪功能,特别是在汛期水库水量较为丰沛期间,灌溉洞电站机组开机,渠首闸执行同时向灌区输水和河道泄水的调度任务时,发电尾水水量的定额分配计算工作十分重要。文章结合运行实例,对渠首闸的调水分水方案作出可行的研析办法。

Luhun irrigation area is the only provincial area in western Henan Province. The calibration and quantitative water delivery work in irrigation area is related to the safety of canal system engineering and water supply. The head sluice in irrigation area has the function of controlling flow and coordinating flood discharge. Especially during the flood season when the reservoir water is abundant,it is very important to calculate the quota of the power generation tail water quantity when the irrigation tunnel power station unit is started up and the head gate performs the dispatching task of the irrigation area water supply and river water discharge simultaneously.Combined with practical operation examples, a feasible analytical method is made for the diversion and diversion scheme of the headgate.
