Fire accidents in underground road tunnels lead to temperature histories characterized by high heating rates and temperatures exceeding 1000°C. This situation results in severe damage of concrete linings as observed during recent fire accidents in European tunnels. This work presents a thermal model to analyse the behaviour under hightemperature of the structure of road tunnels. In particular, the study investigates the temperature distribution inside a 3d model of Zillastro tunnel (Italy) and the effects of different fire-load scenarios on the materials and structure.

Abstract

Fire accidents in underground road tunnels lead to temperature histories characterized by high heating rates and temperatures exceeding 1000°C. This situation results in severe damage of concrete linings as observed during recent fire accidents in European tunnels. This work presents a thermal model to analyse the behaviour under hightemperature of the structure of road tunnels. In particular, the study investigates the temperature distribution inside a 3d model of Zillastro tunnel (Italy) and the effects of different fire-load scenarios on the materials and structure.
