摘　　要：碾压混凝土坝的坝体排水一般采取钻孔、埋设透水管或拔管等方法,对于斜向排水孔,很难保证孔斜的精度,埋设透水管或拔管法对碾压混凝土施工又有较大影响。云镇水库的坝体排水设计通过设置岸坡斜井和水平排水体,全部采用竖直排水孔的钻孔方法,完全避免了对碾压混凝土施工的干扰,钻孔精度也能得到很好的控制。The drainage of RCC dam usually adopts construction methods such as drilling holes,embedding permeable pipes or extubation.For oblique drainage holes,it is difficult to guarantee the accuracy of the hole inclination.Embedding permeable pipes or extubation methods have significant impact on the construction of RCC.The dam body drainage design of Yunzhen Reservoir adopts the drilling method of vertical drainage holes by setting bank slope inclined shafts and horizontal discharge,which completely avoids the interference to the construction of RCC,and the drilling accuracy can also be well controlled.
