Abstract

Fire accident in the ultra-long tunnel could bring significant losses to human lives and economic.In this paper, by using computational fluid dynamics method and the theory of ventilation, physical and mathematical models were established, and a numerical study had been conducted to analyze characteristics of smoke flow near the shield tunneling machine in case of fire. Furthermore, temperature distribution of tunnel field in the middle cross-section of construction was discussed, then corresponding ventilation plans to control the heat around the shield and smoke spread were also extensively proposed, which provide a theoretical foundation to ensure security, and economy of construction in long-distance tunnel.
