The shock generated by blasts inside a tunnel is a complicated phenomenon that the Veneklasen team had successfully dealt with both in terms of its modeling and mitigation. The blast inside a tunnel generates a blast wave that travels through the tunnel. The blast generates a shock wave that eventually decays into an acoustic wave that travels with the speed of sound. The effects of this blast wave include ground-borne vibrations, low-frequency noise, and high-frequency noise. Concerns regarding the negative impact on people and structures from the noise and vibration generated by blasting have been a top priority for such projects.

There is considerable air movement and pressure difference experienced at the shock wave position. The pressure gets translated through the tunnel in the form of ground-borne vibrations. The damage potential of the wave depends on the type of structure, shock-front pressure rise, the force due to impulse, and the vibration magnitude at different frequencies.

Computer simulations and modeling have been developed to determine the potential mitigation solutions/techniques for minimizing the negative impact on people and structures. Veneklasen for the first time has devised a detailed and systematic protocol for the analysis and mitigation of shock and standing waves set up inside a tunnel geometry of any length. Following such a comprehensive analysis, on-field noise and vibration monitoring was performed prior to and after post-deployment of the mitigation methods, for determining the effectiveness of these techniques in the reduction of the frequency components and vibration effects through the shock wave inside and outside the tunnel.
