摘要
Explosion inside the entrance of a tunnel may produce strong blast wave in the tunnel. Taking effective measures to attenuate the air blast wave is very important. Numerical simulations were done on explosion inside the entrance of a tunnel in three different cases, no baffles, symmetrical baffles and stagger baffles arranged along the tunnel. It is found that the arrangement of baffles can attenuate the air blast wave effectively. The best arrangement of baffles is given and it is a reference for tunnel protective design and study.
