Abstract: In order to overcome the problem of poor detection effect due to the failure of the traditional methods to detect damage indicators, a self-compacting concrete damage and crack detection method based on fuzzy analytic hierarchy process is proposed. Construct a concrete damage detection index system and a concrete damage analytic hierarchy model, and determine the evaluation index weights according to the results of the damage analytic hierarchy. The fuzzy analytic hierarchy process is used to calculate the evaluation index, and the final comprehensive evaluation result is obtained to realise the detection of the damage and cracking of the self-compacting concrete. The experimental results show that the highest detection accuracy of this method reaches 90%, and the detection time of this method is short, always less than 1 s, and the detection sensitivity is high. The experimental results can verify the effectiveness of this method.
