| 摘 要： | 在<河流流量测验规范>中,规定了流速仪法测流垂线、流速测点的分布位置和布置测点时的最小水深,1]也有这方面的刊载,并列举了部分计算公式,但公式考虑不够全面,而且还不符合规范要求.本文依据规范,按流速仪测点布置情况,分析推导出了具体完整的计算公式,并对测点布置方案选择提出了相应的建议.

| Abstract: | In the Standard of Channel Flow Measurement,it stipulates the flow metering perpendicular,distribution location of velocity measurement points and the minimum water depth of the flow measurement,with some formulas being provided.But these formulas can not meet the requirement of the standard.Based on the standard and the distribution of current-meters,a specific formula was obtained after analysis,and some suggestions were given. |
