前言多年来,贵州省的大多数渠道均未认真进行渗漏测试,少数渠道曾用动水法进行过测试.由于动水法可靠性差,精度低,且我省渠道工程设计流量小,用流速仪测量的相对误差较大,因此对于全省各类渠道防渗前后渗漏水量的状况,缺乏一个较接近实际的数量估计.根据水电部对贵州省投资计划中对平坝县羊昌河灌溉工程渠道进行静水法渗漏测试的 Preface For many years, most of the channels in Guizhou Province did not seriously leak test, a few channels have been tested by the hydrodynamic method.As the hydrodynamic method is poor, low accuracy, and the flow of engineering design in our province is small, with the flow rate The relative error of the instrument measurement is relatively large, so for the various types of channels around the province seepage water leakage before the situation, the lack of a closer to the actual number of estimates.According to the investment plan of Guizhou Province, Pingba County, Yang Changhe Irrigation Project Channel hydrostatic leakage test
