Evacuation Simulation of the Yangtze River-crossing Highway-metro Integrated Tunnel on Sanyang Road in Wuhan
In response to the evacuation and rescue of fires occurred in the Yangtze River-crossing highway-Metro integrated tunnel on Sanyang Road in Wuhan, the Pathfinder was used to simulate the evacuation of highway tunnels and subway tunnels. The variables in the simulation are: the distance between evacuation stairs in the road tunnel is 50 m, 75 m, 100 m; the width of the evacuation gate in the subway tunnel is 0.9 m and 1.4 m, and the evacuation gates interval is 100 m, 150 m. The research shows that: under the design of traffic conditions, the evacuation time of highway tunnels is mainly affected by the spacing of the slides. The larger the spacing, the longer the evacuation time. In the subway tunnel, the smaller the width of the evacuation gates, the larger the distance between the evacuation gates, the longer the time is; when the top exhaust fails, the interval of the evacuation door is 50 m, which meets the requirements; when the top exhaust is effective, the evacuation gate spacing is 50 m and 75 m, which basically meets the requirements. The simulation provides a reference for the evacuation of the new type of joint tunnel.
