Abstract: The online dam safety monitoring and controlling system of Xinfengjiang hydropower station has established an online technology and method system integrating online monitoring management, monitoring and evaluation, intelligent patrol inspection, online structure safety calculation and evaluation. It comprehensively evaluates dam safety, and is at the top level in research and development of online monitoring and controlling technology for dam safety in China. The detailed scheme of development of the online dam safety monitoring and controlling system of Xinfengjiang hydropower station is proposed, including monitoring content, inspection of timeliness and effectiveness of measured values, index and abnormality identification method for single measuring point, information fusion method, evaluation rules, monitoring and evaluation scheme, patrol inspection and evaluation scheme, structure safety evaluation scheme, and et al. Finally, comprehensive evaluation of dam safety of the hydropower station is obtained.

Key words: dam safety, online monitoring and controlling, intelligent patrol inspection, structure safety, comprehensive evaluation
