渠道渗漏测试方法的选择,不仅决定于测试方法本身的特点、测试精度、适用条件,而且也决定于测试的目的和被测渠道的特点。一、测试方法种类及其特点目前我国现场测试渠道渗漏损失的方法主要有:静水法、动水法和测渗仪法(点测法)。采用静水法测试渠道渗漏损失具有以下特点: (1) 静水法测量渠道渗漏水量用称量法或体积法,是测量渠道渗漏量精度最高的方法之一。采用静水法不但可以测量渗漏量大的渠道,而且在渠道渗漏量相当小的情况下,也可以达到较高的精度。 Channel leakage test method of choice, not only depends on the characteristics of the test method itself, test accuracy, applicable conditions, but also depends on the purpose of the test and the characteristics of the channel under test. First, the type of test methods and their characteristics At present, there are mainly ways to test the leakage loss of on-site test channels in China: static water method, dynamic water method and the method of measuring the seepage (point method). The use of hydrostatic method to test the channel leakage loss has the following characteristics: (1) Hydrostatic method to measure canal seepage water using weighing method or volumetric method is one of the methods to measure the channel leakage amount of the highest accuracy. The use of hydrostatic method can not only measure the leakage of large channels, but also in the case of channel leakage is quite small, but also can achieve higher accuracy.
