ABSTRACT = {Due to the lack of a quantitative basis for the inspection, evaluation, and identification of existing transmission tower foundations, a new fuzzy comprehensive evaluation method is proposed to assess the reliability of transmission tower foundation bearing capacity. This method is based on the reliability analysis of the transmission tower foundation bearing capacity by analyzing the sensitivity of degradation of detection indexes on the reliability of transmission tower foundation bearing capacity, the weighting coefficient matrix is established about the influencing factors in the evaluation model. Through the correlation analysis between the bearing capacity degradation of the transmission tower foundation and its corresponding reliability degradation, the reliability evaluation grading standard for transmission tower foundation bearing capacity is established. The proposed fuzzy comprehensive evaluation method is used to evaluate the reliability of a 500 kV transmission tower foundation bearing capacity and to verify the rationality of the new evaluation method. The research results can provide a foundational framework for the detection and evaluation of transmission tower foundations and can serve as a reference for the development of structural reliability evaluation methods.},
