摘要：
With the rapid development of the economy, underground utility tunnel has become an important infrastructure and "lifeline" for major cities. Through the investigation of the fire form of the pipe gallery, it was found that the most dangerous fire in the underground utility tunnel is the integrated pipe gallery power cabin, which is mainly represented by cable fires. This paper mainly focuses on the special T-shaped structure of the underground pipe gallery. The FDS software is used to simulate the occurrence of cable fires, analyzing the temperature field change of the corridor and the temperature of the ceiling of the T-shaped corridor with the changing of the fire source power. The cable fire is how to spread at the T-junction. The situation results provide a certain reference for the actual fire extinguishing of underground T-shaped cable duct corridors.
