EXPERIMENTAL EVALUATION OF THE EFFECTS OF A CONCRETE BARRIER TO PRESSURE WAVE PROPAGATION

Abstract eng:
This paper presents the results of an experimental program focused on measuring the parameters of the blast wave resulting from explosive detonation and possibilities of influencing propagation of this blast wave in order to minimize risk of injury of people near the explosion. Multiple arrangements of solid blast barriers are proposed and experimentally evaluated. The results obtained from the experiments are presented and explained. Thanks to the use of TNT charge, the experimental results can be directly compared to data derived from other blasts without barriers. That presents a valid basis for determination of the overall barrier effectiveness in reducing overpressure at the front of the blast wave.
