Abstract: Through the case analysis of arch dam failure, the structural characteristics and the online safety evaluation of super high arch dam are studied, and a safety evaluation model is developed. By comparative analysis of various information fusion methods, it is considered that the rule inference method is the most applicable to judge dam safety. A rule inference system is established based on Guide for safety assessment of large dams for hydropower station in operation, and then the online security evaluation platform is developed. The research results have been applied to Jinping Ⅰ arch dam, and the results show that the online safety evaluation platform can evaluate dam safety status in real time and accurately.

Key words: super high arch dam, online safety evaluation, information fusion, rule inference
