During service life, road tunnels may face threats of accidental explosions, eg, Boiling Liquid
Expansion Vapour Explosions (BLEVEs) due to accidents of vehicles transporting
hazardous goods inside the tunnels. However, very limited study has investigated the
influence of BLEVEs inside a tunnel on its dynamic response. The present study numerically
investigates the dynamic response of an arched tunnel subjected to an internal BLEVE by
using the software LS-DYNA. The BLEVE load is directly simulated by using commercial …
