Analysis on cable fire spread and temperature distribution in T-shaped cable tunnel
The complex structure， poor ventilation as well as large number of cables impose risks to the operation of urban cable tunnels. Among the cable tunnel accidents， cable fire is the primary disaster imperiling power transmission and urban safety. FDS （fire dynamics simulator） is used to simulate the i...

| description | The complex structure， poor ventilation as well as large number of cables impose risks to the operation of urban cable tunnels. Among the cable tunnel accidents， cable fire is the primary disaster imperiling power transmission and urban safety. FDS （fire dynamics simulator） is used to simulate the influence of underground cables on the occurrence and evolution of cable fire in T-shaped cable tunnel. Moreover， the influence of cable shaft location change brought about by the underground cable amount on temperature distribution and heat release rate （HRR） is analyzed. The results can be used as a reference for designing fire prevention and fire extinguishing devices for underground T-shaped cable tunnels. |
