固定式多探头雷达波测流系统在缸瓦窑水文站的应用研究

Application Research of Fixed Multi-probe Radar Wave Measurement System in Gangwayao Hydrological Station

近年来,各河流出现超标洪水的机率大大增加,而水文站超标洪水的水文测验是一个簿弱环节,需找到解决的方法。通过在缸瓦窑水文站引入安装固定式多探头雷达波测流系统并进行比测率定分析,得出断面平均流速与指标流速的相关关系式为:V_(平均)=0.0379 V_(LD)^(2)+0.2619 V_(LD)+0.3954,复相关系数R^(2)=0.9813,随机误差为6.8%≤8%,关系式通过水位流量曲线三线检验,投入使用后能有效解决缸瓦窑水文站超标洪水时水位、流量测验自动化问题。

In recent years,the probability of excessive floods in various rivers has greatly increased,and the hydrological survey of excessive floods at hydrological stations is a weak link,and a solution needs to be found.By introducing and installing a fixed multi-probe radar wave measurement system at the Gangwayao hydrological station,and performing comparative analysis.The relationship between the cross-section average flow velocity and the index flow velocity is obtained as follows:V_(average)=0.0379 V_(LD)^(2)+0.2619 V_(LD)+0.3954,multiple correlation coefficient R^(2)=0.9813,random error is 6.8%≤8%.The relationship has passed the three-line test of the water level and flow curve.After being put into use,it can effectively solve the automatic problem of water level and flow test when the Gangwayao hydrological station exceeds the standard flood.
