At present, the tunnel design specifications in China do not provide a clear and systematic intelligent evaluation system of frost damage cold regions. Based on research results 122 seasonal frozen soil tunnels high-latitude areas China, four key influencing factors geohydrology, temperature, surrounding rock, engineering measures were determined, fuzzy comprehensive model was established, weights all considered, technology had been put forward. Meanwhile, rationality verified by specific case. The suggests that proposed this paper can accurately describe relationship areas, weight each factor is calculated using analytic hierarchy process, main risk sources are found out. an efficient practical method for Intelligent prediction damage. By subordinate function method, improvement from qualitative analysis to quantitative index calculation realized. blindness analogy construction avoided, scientificity accuracy renovation have improved. same time, theoretical basis
