Cable Tunnel Fire Detection Technologies Research

摘要

Various types of fire detection technologies for road tunnel protection were studied in this paper based on the Full-Scale Fire tests as the major method.A unified performance index was established and the cable tunnel fire detection model was developed based on the analyze the statistics of the tunnel fire and simulation tests. Cable linear fire detector, fiber grating fire detector and distributed fiber fire detector was respectively used to do the contrast tests. Tests results showed that the detection capability of the fiber grating or distributed fiber fire detectors was only better in some one factor and in general the cable linear fire detector had a good performance in fire detection.
