Abstract

Abstract: FDS full-scale fire numerical simulation model was established based on the standard section of the utility tunnel of Chengbei road in Suzhou. The fire development situation and temperature distribution law of the power cable compartment fire in the utility tunnel were simulated and analyzed. Four layers of cables were set on the left and right sides of the pipe gallery, the influence of the fire barrier on the fire development and temperature distribution was studied by 2 scenarios of with or without fire barrier. The results showed that when there is no fire barrier, the development direction of the fire in the utility tunnel is mainly transverse spread, and the top cable burns with the expansion of the fire and the heat transfer of smoke accumulation,and finally spreads to other areas of the utility tunnel. The vertical fire spread time was delayed by about 40%,and the maximum temperature in the utility tunnel was reduced by about 18% by setting the fire barrier.
