摘要
本文以2020年1-3月界首水文站缆道流速仪法实测流量数据为依据,精简位于主航道中心(即起点距95.0 m)处测速垂线,保留其测深垂线,重新计算断面流量,建立精简测速垂线前后两组流量数据之间的相关关系,对两组数据进行误差分析,确定其可行性。经计算分析,精简测速垂线前后断面流量关系良好,各项计算指标均在允许范围,界首水文站可以精简位于主航道中心(即起点距95.0 m)处测速垂线,保留其测深垂线,实施断面流量测验。
In this paper,based on the measured discharge by the cableway current meter method at Jieshou Hydrological Station from January to March in 2020,the vertical line of velocity measurement could be simplified at the center of the main channel(the starting point distance is 95.0 m),and the section flow was recalculated by retaining the depth measurement vertical line,the correlation between the two groups of flow data before and after the simplified of vertical line of velocity measurement was established,and the errors of the two sets of data was analyzed to determine its feasibility.Through the calculation and analysis,the relationship between the cross-sectional flow rate before and after the simplified speed measurement vertical line was good,and all the calculation indexes were within the allowable range,therefore,the vertical line of velocity measurement at the center of the main channel(the starting point distance was 95.0 m)at Jieshou Hydrology Station could be simplified,and the section flow could be measured with vertical line kept.
