According to the characteristics of subway construction in Tianjin, a risk assessment indicator system has been established in subway construction. On the basis of traditional AHP (Analytic Hierarchy Process), the introduction of the concept of triangular fuzzy numbers evaluates the weight of risk factors in a more accurate and objective way. Adopting a fuzzy comprehensive evaluation mathematical model, by constructing membership matrix, the metro construction is not difficult to quantify the risk factors with the scientific evaluation methods. It can be proved that fuzzy comprehensive evaluation method used in subway construction process is a scientific, effective evaluation method.
