摘　　要：景洪水电站大坝12~13号坝段570 m高程廊道顶部结构缝出现渗漏。为查明渗漏原因,采用水下遥控潜航器(ROV)携带高清摄像头、图像声呐、水深计、示踪剂等对坝段结构缝、层间缝及混凝土表观进行水下检查。通过水下检查确定渗漏入口,为渗漏病害治理方案设计提供依据。In order to find the source for seepage at the structural joints of gallery top on elevation 570 m between dam section No.12 and No.13 of Jinghong hydropower station,underwater remote operated ve?hicle(ROV)carrying high-definition camera,image sonar,bathometer and tracer is used to acquire un?derwater video and image for inspection of the structural joints and concrete appearance.The seepage path is found which provides basic support for subsequent leakage treatment,worth reference.
