摘要
回顾了国内在渠道动水法测渗问题上观点分歧的由来和实质,分析了动水法的测渗误差,并着重讨论了上下测流断面的距离及测试次数对相对误差限的影响,最后建议应修改国家规范GB/T50363-2006中有关动水法问题的规定。
In this paper, the origin of opinion difference and the controversy substance about current-meter method to measure canal seepage amount in our country are reviewed. The measure error is analyzed and the influence of the distance from the upper discharge measuring cross-section to the lower cross-section and the measurement times on the relative error limit is discussed emphatically. Finally, the suggestion about modifying the content related to current-meter method in national specification GB/T50363-2006 is presented.
