Abstract: The study of material failure phenomena with coupled multiple scales is a need and a challenge. The fundamental difficulty in these problems is due to multiscale bridging material parameters and damage, which ensure that ...

Abstract: Because it is impossible to predict the temperature in advance, specific fire scenes (fire type, fire location, tunnel geometry, etc.) are unknown in traditional tunnel fire research. To address this difficulty, this work ...

Abstract: Because of their adverse impact on social infrastructure and economic property, gas explosions are among the most dangerous disasters that can befall utility tunnels. Flame propagation is the most intuitive manifestation ...

Abstract: The enhanced burning intensity of double fires in utility tunnels resulting in accumulated smoke and heat can lead to heavier casualties. For a single fire source with an end wall, the end wall causes reflections of smoke ...

Abstract: With the rapid development of utility tunnels, fire safety after construction is increasingly important, especially in the cable compartment. An intelligent fire detection method based on the particle swarm optimization ...
