常州市老城区小型泵闸站过闸流量估算方法

Research on the estimation method of crossing flow of small gate stationin Changzhou City

工程管理一线计算过闸流量通常存在经验公式种类繁多,水流形态不易分辨,各项系数难以确定,计算所需实测数据缺失等问题,简单且较为精确的小型泵闸站过闸流量计算方法既有利于运管单位的日常管理,也可以为评估市区调换水工作的开展进程提供理论依据。通过简化传统水力学公式,并以常州市运北片防洪包围圈上的15座水利枢纽的过闸流量作为校核标准,检验简化公式的实用性,探寻老城区建设资料或者观测设备不齐全的小型泵闸站过闸流量的简易计算方法。

There are usually problems as a variety of empirical formulas,water flow patterns difficult to distinguish,various coefficients difficult to determine,and missing the measured data required for calculation,and so on in project management front-line calculation of gate flow.Simple and accurate calculation methods for gate flow of small pump gates is beneficial to the daily management of the transportation management unit,and can also provide a theoretical basis for evaluating the progress of urban water exchange work.By simplifying the traditional hydraulics formula and taking the flow through sluice of 15 water conservancy projects in Yunbei Area of Changzhou City as the check standard,the practicability of the simplified formula was tested,and a simple calculation method for the flow through gate of the old city construction data or small pump gate stations with incomplete observation equipment was explored.
