武思江大江口站新旧规范测流方案对比分析

Contrasting and analyzing the flow measurement schemes of the Wushijiang river Dajiangkou station between the new code and the old

首先按照《水文测验手册》的要求，对大江口水文站的精测资料进行测点和垂线分别精简的分析，确定该站常测法测流的方案。然后按新规范国标ＧＢ５０１７９ － ９３《河流流量测验规范》的要求对所定的两种测流方案的误差进行统计，发现旧规范可行的方案并不一定能满足新规范的要求，因此有必要对水文站现行的测流方案进行重新分析、选择，确保我们使用的测流方案既高效也符合新规范的精度要求。

According to hydrology test handbook,the authors analyzed the measurement materials of the Dajiangkou station and determined the flow measurement scheme. By the new state code,river flow test code (GB 50179-93),through analyzing errors,the author thought that the present flow measurement scheme should be analyzed and selected anew to make sure the test scheme being able to meet the precision and efficiency requirement of new code.
