固定水位静水测渗法,是早为人们肯定的渠道测渗方法.石津灌区在1982年以前,用传统的定水位静水测渗方法,测量渠道渗漏损失.该法可以通过延长固定水位测试时间来提高测试精度,固定在一个水位的时间越长,其成果精度越高.和原变水位静水测渗法相比,成果可靠的多.但此法耗用时间长、费用高,对渗漏量大的大断面更难以施测.其成果也只代表施测渠本身的施测水位.而运行中的渠道水位又是经常变化的,所以成果的使
The fixed water level hydrostatic seepage test method is an affirmative test method for measuring the channel penetration.The Ishizu irrigated area measured the seepage loss of the canal by the traditional constant water level hydrostatic test before 1982. The method can be extended the fixed water level test time To improve the test accuracy, the longer the time fixed in a water level, the higher the accuracy of the result.Compared with the original water level hydrostatic infiltration test, the result is more reliable, but this method consumes a long time and high cost, The larger the large cross-section more difficult to test its results also represent the test channel itself, the test water level while the operating channel water level is constantly changing, so the results of the
