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 the drainage capacity of each sluice in Fengxian District and the water flow direction and water quality improvement in the river carrier in the area after the floodgate was opened, experimental study on water diversion of diversion and drainage of gate group was carried out. Based on the analysis of the design capability of floodgate and the difference of current operation, the method of estimating discharge of sluice group was evaluated, and the rate of increase of water level in heavy rainstorm and riverbed was calibrated. The average amount of water per 1cm of river level was 787,000 m ~ 3, to provide a scientific basis for the control of Fengxian District Gate Group.
