古田溪一级电站引水隧洞充排水试验

Water Filling and Draining Test of Diversion Tunnel of Gutian Creek First Grade Power Station

引水隧洞充排水试验是水电站建设的里程碑事件。充排水试验是对水电工程整体结构、建造质量的考验。充排水试验一般需间歇充水,分级稳压,通过分析古田溪一级电站引水隧洞充排水试验步骤及其成果,可对类似工程提供借鉴。

The filling and draining test of diversion tunnel is a milestone in the construction of hydropower station.The test of filling and draining is a test of the overall structure and construction quality of hydropower projects.The filling and draining test usually requires intermittent water filling and grading stable pressure.This paper mainly introduces the steps and results of the water filling and draining test of the diversion tunnel of Gutian Xi first grade power station, which is of reference to similar projects.
