Abstract

In this study, the propagation of a pressure wave inside a tunnel due to explosion near the blast proof door is investigated. In addition, the peak pressures and its arrival time are measured experimentally. Trinitrotoluene of 12 kg was detonated in front of a 20 mm thick steel blast proof door. Based on the experimental data, a finite element analysis was performed to analyze the pressure wave propagation phenomena inside the tunnel. The experimental measurements with four peak pressures match up well with the finite element analysis results. Additionally, the finite element analysis clearly showed pressure wave propagation sequence inside the tunnel. As it is difficult to explain the pressure wave propagation phenomena through experimental results, the finite element analysis can be useful for supporting the complex analysis.
