Abstract: On-site dam safety inspection of hydropower stations is as important as monitoring by instruments, in which major abnormal phenomena would be detected, which provides reliable basis for elimination of major hidden risks. Based on actual situation of dam safety management in Dadu river basin, this paper systematically summarizes the mechanism and concept of on-site dam safety inspection and management of cascade hydropower stations in the basin. By construction of standards system for dam safety management, based on the professional groups, technical supervision, information technology and the standardization of safety practice, the on-site dam safety management has been significantly improved. At the same time, the innovative application of UAV aerial survey and patrol technology, digital patrol inspection technology, defect detection technology for hydraulic structures, InSAR large-scale survey technology, LiDAR technology and high-resolution remote sensing technology has improved the intelligence of field safety inspection, and transformed the field inspection from traditional manual inspection to remote inspection, which is digital, intelligent, multi-dimensional and fully covered, worth reference.
