AHP and Casualties Calculation Based Research on Road Tunnel Fire Risk Evaluation

Abstract

On the basis of classic risk theories this paper proposes a more pertinent and practical fire evaluation model for road tunnels. According to causes for tunnel fire, an index system for assessment of tunnel fire probability and rating criteria are established based on tunnel properties, environmental conditions, traffic status and vehicle performance. By fine modelling of tunnel fire smoke spread and personnel escape behaviour, a calculation method and rating criteria for consequences of tunnel fire are established. The research results suggest this method is a feasible means to assess road tunnel fire risks.
