Abstract: In order to check the construction quality and detect possible problems, before the commissioning of generating units, the water charging and discharging test of No.1 water diversion system of Jinping Ⅱ hydropower station was conducted. During the test, the surrounding rock deformation, seepage pressure and seepage discharge were monitored. The test results showed that the safety of main structures was normal, the design and construction quality were good and the structures were reliable as well.
