【 摘 要 】

Road tunnel, as an underground engineering, is characterized by unpredictability which has high fire risks in operation process. In recent years, major fire accidents have happened around the world in road tunnel operation process, causing enormous casualties and economic losses. Therefore, it is very necessary to assess fire risks during the road tunnel operation process. In this paper, an index system of road tunnel fire risk assessment with different categories of assessment indexes is established. Index weight is introduced to show the importance of each assessment index for assessment object. This paper adopts fuzzy analytic hierarchy process (FAHP) to express index weight with qualitative description language through pairwise comparison. Qualitative description language given by experts are indicated by correlative triangular membership function. Finally, through defuzzification and normalization, triangular fuzzy numbers are converted into final weights to establish the fire risk assessment index system during the road tunnel operation process.
