摘要
讨论分析了目前国内外常见的几种流速面积法实测流量的计算方法。根据我国的流量测验情况,对精度较高的丁文昌法进行了改进,使之与我国的流量测验情况更加适应。提出了一种与《河流流量测验规范》(GB50179—93)测深、测速垂线布设原则相适应的实测流量计算方法。
This paper analyzed and discussed the national and international common methods of observed discharge calculation.According to Chinese situation of discharge measurement,the high accuracy of Dingwenchang method was improved so as to meet the requirement of dis-charge measurement in China.Then,a discharge measurement method was suggested based on Code for Liquid Flow Measurement in Open Channels（GB50179-93）.
