Abstract: Increasingly, deep tunnels are under construction, which greatly promotes the development of tunnelling technology. Complex geological conditions and frequent geological disasters have become great challenges during tunnel excavation. Among them, casualties and economic losses caused… read more here.

Abstract: Abstract Maximum temperature rise is an important parameter in tunnel fires. It is noted that classical models of maximum temperature rise in previous studies are limited to single tunnel. However, in real situations, there is… read more here.
