锦屏二级水电站1号引水系统充排水试验监测资料分析

Data analysis on water charging and discharging test of diversion system No.1 of Jinping Ⅱ hydro power station

为检查锦屏二级水电站1号引水系统施工质量,查找可能存在的问题,在水轮发电机组投产发电前,选择适当时机进行了充排水试验。试验过程中,重点监测各部位围岩变形、渗流渗压及渗漏量等情况。试验监测成果表明,锦屏二级水电站1号引水系统各主体工程安全状态基本正常,设计布置合理,施工质量良好,结构可靠。

In order to check the construction quality and detect possible problems, before the commis- sioning of generating units, the water charging and discharging test of No. 1 water diversion system of Jin- ping 11 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 struc- tures was normal, the design and construction quality were good and the structures were reliable as well.
