1 问题的提出在平原地区水闸过闸流量的计算公式非常麻烦,其中的一些系数都需要查阅工具书;另外,水利工作的野外工作量占有一定的比重,在野外往往没有工具书可查;再加上乡村及灌区基层管理单位的工作者,大部分业务水平较低,对于运用宽顶堰流量公式有很大的困难。因此,拥有一个简便、实用的水闸过闸流量的计算公式是非常必要的。2 解决问题的思路水闸过闸流量的计算公式:Q=σsεmB(?)H_0~(1/2)
1 PROBLEM PROBLEMS The calculation formula of sluice gate flow in plain area is very troublesome, some of them need to refer to reference books. In addition, the workload of field work in water conservancy accounts for a certain proportion and there is often no reference book in the field. Coupled with the low level of most of the workers in rural areas and grassroots management units in irrigation districts, it is very difficult for us to apply the formula of wide crest weir. Therefore, it is necessary to have a simple and practical formula for calculating the gate lock discharge. 2 ideas to solve the problem Gate sluice gate flow calculation formula: Q = σsεmB (?) H_0 ~ (1/2)
