| 摘 要： | 为了研究在测深杆悬挂流速仪法实测流量时,水深观读误差对流量成果精度的影响,作者采用实例数据进行了对比分析。结果表明,在测深杆迎水面和背水面观读水深时所产生的误差都会给流量测验精度带来较大影响,而且会引起水位～流量关系曲线的明显偏离,给流量资料整编成果带来较大误差,在一定程度上降低了河流流量资料的使用价值和精度标准。针对误差来源,提出了减少水深测量误差的具体建议。

| Abstract: | In order to study the effects of error resulted from water depth observation and reading on discharge result accuracy when the hydrodynamometer method of suspended sounding rod was used to observe the discharge,the author adopted the actual data to compare and analyze them in the study.The results show that the error caused by sounding rod as observing and reading the water depth on upstream and downstream slopes may effect seriously the tested accuracy of discharge,furthermore,leading to the water level ~ ... |
