Abstract：To assess the health status of the diversion tunnel lining accurately,a comprehensive evaluation index system was developed.Cloud model theory was applied,with an improved AHP and entropy weight method used to calculate subjective and objective indicator weights,which were then combined using game theory.The health evaluation method for diversion tunnel linings,based on cloud models,addresses both the fuzziness and randomness of indicators while effectively managing contradictions and conflicts among them.This approach enhances its theoretical rigor and reasonableness.Using a water diversion tunnel in the northwest region as a case study,the engineering application demonstrated that the evaluation results matched the actual conditions,thereby validating the model's effectiveness.This offers a clear and scientific approach for assessing the health status of tunnel linings.
