堰闸流量资料整编,多采用流量系数法。由于算得的流量系数是一个变量,因而整编成果不利于电算推流。尤其是沉溺式出流的流量系数的相关因素比较复杂,成果点据散乱,精度不高。为此提出用逐步图解法直接分析流量计算公式,以便于电算整编推流,提高成果精度。最后根据图解求得的流量计算公式,再用水力学出流公式分析流量系数,从而分析它的变化规律。
Weir gate flow data reorganization, and more use of flow coefficient method. Since the calculated flow coefficient is a variable, the result of the reorganization is not conducive to the flow of electricity. In particular, the related factors of the flow coefficient of indulging outflow are complicated, the results are scattered and the accuracy is not high. Therefore, the direct calculation of flow calculation formula by step graphic method is put forward in order to facilitate the reorganization of data flow and improve the accuracy of results. Finally, according to the graphic calculation of the flow calculation formula, and then use the hydraulic flow formula to analyze the flow coefficient, so as to analyze its variation.
