摘　　要：清江水布垭面板堆石坝施工过程中,大坝面板由于受混凝土干缩、温度应力及堆石坝体沉降变形的影响,使大坝面板产生了不同程度的裂缝,从宏观上分析了裂缝的成因,对裂缝进行分类,提出了限制面板裂缝发生的措施,并针对不同类型裂缝性质、裂缝宽度,制定了切实可行的处理方案,面板裂缝经修补后,都呈闭合状态,大坝面板可满足工程安全运行需要。Due to concrete dry shrinkage,temperature effect and rockfilled dam body settlement,the dam face of Shuibuya Hydropower Station on the Qingjiang River cracked at varying degrees in the construction period.We analyze the crack genesis macroscopically.The cracks are classified and practical treatment scheme is presented in the light of different crack types and crack widths.After treatment,the concrete face cracks are all in closed state,which meets the requirement of project safe operation.
