摘　　要：该文从瓦屋山水电站压力引水隧洞裂缝基本性态出发,采取不同检测手段,从砼施工质量、周围岩石变形特性及地震影响等方面进行了裂缝成因综合分析,针对不同类别的裂缝采取了相应修补方法,取得了较好效果。With the vigorous development of hydropower clean energy,concrete pressure diversion tunnel is widely used in the power plant construction. On basis of the basic state of cracks in the pressure diversion tunnel of Wawushan hydropower station,adopting different detection techniques,a comprehensive analysis has been made on the causes of cracks from aspects of concrete construction quality,deformation characteristics of the surrounding rocks and seismic effects etc. It takes appropriate repair methods against different types of cracks,and achieves good results.
