Simulation Study on Value of Cable Fire in the Cable Tunnel

The cable tunnel fire spreads rapidly, the high-temperature toxic smog accumulates, and the fire fighting is of great difficulties. Once the fire hazard occurs, serious economic losses and casualties will be caused. Through the numerical simulation of the cable tunnel fire process, and the analysis and summary of simulation results, conclusions are drawn of flue gas spread situation and the section temperature changes during the generating process of cable tunnel fires. Then the best fire fighting time is proposed, which provides references for development of fire-fighting measures and selection of the fire protection system.
