Research of fire district throttling effect theory and testing in road tunnel fire
Zhou Renqiang · Sichuan Building Science · 2009
Fire district throttling effect has always been a typical phenomenon in road tunnel fire.Researching the throttling effect of road tunnel fire and its modifying factors is vitally important to properly stimulate fire,analyze the development of disaster and guide rescue work.By means of large-scale fire model test,the relationship among throttling effect,ventilation speed and fire's scale has been deeply studied.The pilot tunnel's interior diameter is 1.8 m and it is 100m long.Taking CAN which reaches the world leading level,—an effective support for distributed real-time control and the control of the serial communications network as my data acquisition system,by rationally analyzing and calculating the fire district throttling effect,I conclude that the theoretical formula results coincide perfectly with the corresponding test results.And thus,the validity of the theoretical formula has been proved.
