【Abstract】In combination with structural design, structural status and disease, and maintenance, the special analysis of typical risk events of tunnel structure is carried out for structural safety during operation. At the same time, the evaluation index of structural safety of long highway tunnel is put forward, and the classification standard of tunnel evaluation index is established. The combination weighting method of multification scale method and entropy weight method is adopted, and the weight of each index in the index system is determined by combining the variable weight method. On the basis of this method, the analytic hierarchy process (AHP) and fuzzy principle are used. Finally, the evaluation system and classification standard of the safety level of highway tunnel structures are established.
