摘要

Abstract

T-shaped utility tunnels are long

narrow confined spaces with intersections. During a fire

smoke can propagate through multiple pathways

and ventilation schemes can influence smoke flow direction

thereby increasing fire accident risks. To investigate how changes in fire source location affect visibility in T-shaped utility tunnels under differe

nt ventilation schemes

a model was established using Pyrosim software. The result show that under ventilation scheme

fire source position 1 has the greatest impact on visibility; under ventilation schemes

and

fire source position 4 has the greatest impact on visibility; under ventilation scheme

fire source position 3 has the greatest impact on visibility.
