| Abstract: | The paper established an integrated evaluation model and factor system of long-span CFST arch bridge on the basis of Analytic Hierarchy process. It created a synthetical evaluation method to evaluate the safety of long-span CFST arch bridge, citing with Fuzzy Theory. The method is proved feasible and practical through being applied to the practical project, with an intuitionist and simple result of evaluation reflecting the safety status of existing bridge. |

| Keywords: | CFST arch bridge multilevel fuzzy integrated evaluation safety evaluation |
