摘　　要：2016年清江隔河岩大坝遭遇百年一遇洪水袭击,大坝泄洪对下游护坡造成多处损毁。根据护坡不同损坏类型的检测与成因分析,分别采用了锚杆加面层钢筋网混凝土、M30预缩砂浆、高弹性环氧嵌缝材料直接灌缝等多种技术措施进行修复处理,取得了较好效果,可供类似工程参考。In 2016,Geheyan Dam on Qingjiang River was affected by a once-in-a-century flood.The downstream slope revetment of the dam was damaged seriously due to the flood discharge.Considering the different damage types of the slope revetment and the different causes,various repair and reinforcement techniques were adopted,including the anchor rod combined with surficial reinforcement mesh concrete,M30 preshrunk mortar,and direct joint grouting with high elastic epoxy.Satisfactory repair performance was achieved.It provides useful reference for similar projects.
