过去采用流量系数法整编堰闸流量资料,由于算得的流量系数是一个变量,因而其成果不利于电算推流。尤其是沉溺式出流的流量系数,相关因素比较复杂,成果点据散乱,精度不高。为此,提出以多元对数图解法(又称逐步图解法)整编堰闸流量资料。经我省部分堰闸站(包括感潮堰闸站及电力抽水站)的整编实践证明,成果精度比较满意,且便于电算整编推流。现介绍于下,以供参考。
In the past, the flow coefficient method was used to integrate the weir flow data. Since the calculated flow coefficient is a variable, the result is not conducive to the flow of electricity. In particular, the flow coefficient of indulgence type outflow, the relevant factors are more complex, the results are scattered, the accuracy is not high. To this end, proposed by multivariate logarithm graph (also known as step by step graphic method) reorganization weir gate flow data. Proved by the reorganization of some weir gate stations (including the tide-pressure weir gate stations and electric pumping stations) in the province, the accuracy of the results is satisfactory and it is convenient for the computer-based reorganization to push the stream. Now introduced below, for reference.
