代表垂线法在中高水流量测验方案的应用

Application of Representative Vertical Method in Medium and High Flow Measurement

本文依据谷城站2007-2010年实测流量资料、测验河段及河道断面的特点,针对上游电站泄流频繁、水位涨落急剧情况,提出中高水流量测验方案中采用代表测速垂线与断面平均流速间的综合关系,提出适合该站水流特性的中高水流量测验方案,验证该方法的可行性和有效性。

According to the measured flow data,the characteristics of the measured river reach and river section of Gucheng Station from 2007 to 2010,and in view of the frequent discharge and sharp fluctuation of water level in the upstream power station,a comprehensive relationship between the vertical line of velocity measurement and the average velocity of cross section is proposed in the middle-high flow measurement scheme,and a middle-high flow measurement scheme suitable for the flow characteristics of the station is put forward to verify the feasibility of the method.And effectiveness.
