摘要
将大闸调度对河网排涝的影响进行分区研究具有重要意义。临海浦江大闸和陶家路江大闸是姚北平原河网排涝的两个重要大闸,为充分研究姚北平原河网出海大闸的排涝作用,以余姚平原河网平面二维数学模型为基础,计算得到一定条件下其不同区域水位和流速的变化数据,按照水位下降0.05m的幅度,根据不同的数值区间,对大闸排涝对姚北河网排涝的影响区域进行了分类,得到了大闸调度对姚北河网排涝影响的7个分区,进而根据此分区分析了区域河网排涝对策,为乡镇街道排涝决策提供参考依据。
It is of great significance to study the influence of sluice dispatching on drainage of river network.Pujiang Sluice and Taojialu Sluice in Linhai are two important sluices in river network draining in North Yuyao Plain.In order to fully study the drainage effect of the sea sluices in North Yuyao Plain,a two-dimensional mathematical model is adopted to calculate the data of water level and flow velocity under certain conditions.With the fall of water level at 0.05 m,the influence regions of sluice drainage of river network in North Yuyao Plain are classified according to different numerical intervals,and seven regions of sluice operation on river network drainage in North Yuyao Plain are obtained.The drainage countermeasures of regional river network are also analyzed according to the regionalization,which provides a reference basis for the decision-making of town and street drainage.
