摘　　要：为确保水库混凝土面板堆石坝长期稳定,文中以贵州某小(一)型水库为例,对混凝土面板堆石坝坝体排水系统设计及施工技术深入探析。结果显示,排水孔的平均、高峰和低谷期排水量均达标,系统平均水压力为1.5 kPa,低于设计安全阈值2.0 kPa;实际平均总渗水量为15 m^(3)/d,比设计预期减少25%;防渗帷幕的渗透率为0.02,显著优于设计值0.05,表现出良好的防渗效果。In order to ensure the long-term stability of concrete face rockfill dam in reservoir,this paper takes a small(1)type reservoir in Guizhou province as an example to deeply explore the design and construction technology of the dam body drainage system of concrete face rockfill dam.The results show that the average,peak and trough water displacement of the drainage holes are up to standard,and the average water pressure of the system is 1.5 kPa,which is lower than the designed safety threshold of 2.0 kPa.The actual average total water seepage is 15 m^(3)/d,which is 25%less than the design expectation.The permeability of anti-seepage curtain is 0.02,which is significantly better than the design value of 0.05,showing a good anti-seepage effect.
