摘　　要：为了在洪水中能及时监测到长坪水文站的水位流量信息,并提高水文站水文测报自动化水平,提高测报一体化服务能力,在长坪水文站安装固定式双探头雷达测流系统并进行比测率定分析,得出断面平均流速与左右探头流速的相关关系为:V_(m)=0.5655×V_(i右)+0.5922×V_(i左)-0.3248,标准差为3.3%,系统误差为0,关系式通过水位流量曲线三项检验。结果表明,长坪水文站水位在233.59~234.78 m范围内,可以采用固定式双探头雷达测流系统监测。In order to timely monitor the water level and flow information during floods at Changping Hydrological Station,improve the automatic level of hydrologic measurement and reporting at hydrological stations,and enhance the ability to provide integrated measurement and reporting services,a fixed dual-probe radar flow measurement system was installed and comparative measuring calibration analysis was conducted at Changping Hydrological Station.The obtained correlation between the mean cross-sectional flow velocity and the velocity out of the left and right probes is V_(m)=0.5655*V_(iright)+0.5922*V_(ileft)-0.3248.The standard deviation is 3.3%and the system error 0.This correlation equation is verified by three items of water level-flow curve tests.The results of comparative measurement demonstrate when the water level at Changping Hydrological Station is within the range of 233.59~234.78m,the fixed dual-probe radar flow measurement system can be used for monitoring.
