    Abstract
  • In order to eliminate the influence of fire smoke on people in single highway tunnel with subtended traffic, a fire numerical calculation model was established.The theory of fuzzy control was introduced into the control of fire smoke, and the reciprocating motion of smoke in the area of 200 m between two groups of jet fans in the tunnel was simulated.By changing the wind velocities and directions of jet fans in tunnel, the distribution and influence law of smoke within the control area were studied when smoke diffusion times were 180 and 360 s, and wind velocities were 1.0 and 1.5 m·s-1.Calculation result shows that after jet fans on both sides of fire source are started respectively, the smoke is basically controlled at the positions of 50-80 m on both sides of fire source, and its motion belongs to small amplitude motion when the start interval of jet fans is 30 s and wind velocity is 1.0 m·s-1.When the interval is 60 s and the speed is 1.5 m·s-1, the smoke is basically controlled at the positions of 80-100 m, and its motion is large amplitude motion.The small amplitude motion is superior to large amplitude motion.
