摘要
文章根据2009和2010年三堆子水文站比测试验资料,进行指标流速段的选取和相关关系的建立,确定流量推算方案,探索H-ADCP在长江上游山区性河道不同水力条件和水流特性下,特别是在不同含沙量级的测验适用条件和适用范围,从而检验H-ADCP在不同水沙条件下运用的精度,探索H-ADCP作为一种测流的基本方法和手段的可行性。
Based on the comparing measurement test data of Sanduizi hydrologic station in 2009 and 2010, the paper selects the range of index velocity and establishes the relationship, determines the scheme of flow calculation, searches the applicable conditions and ranges of H -ADCP under the different hydraulic conditions and flow characteristics, specially the different sediment concentration level, in upper mountainous channel of Yangtze river basin. Then the application precision of H-ADCP is tested in the different water and sediment conditions, which could searches the feasibility of using H-ADCP as the methods and means of the flow measurement.
