摘要
为了解奉贤区各水闸的引排水能力和闸群开启后区域内河道载体中水流的分向与水质改善状况,进行了闸群引排水的调水试验研究。通过对闸群的排涝设计能力与现状运行差异的分析,对水闸群引排水量的估算方法进行了评价,并对大暴雨与河道水位升幅状况进行率定,推算河道水位每上涨1cm时的平均水量为78.7万m^3,为奉贤区闸群的调控提供科学依据。
In order to understand diversion and draining capacity of sluice group in Fengxian District, current direction and water quality improving of rivers where sluice group had been opened, large quantity experiments on sluice regulation and control of diversion and draining were studied. In the article, differences between design drainage capacity and status quo were analyzed, the estimation method of sluice group drainage quantity was evaluated, and torrential rain and river water level increase were calibrated. Furthermore, it was calculated that average water content was 787000 m3 as the river level rising lm, it also provided scientific basis for sluice group regulation and control of Fengxian District.
