The effect of structure shape variation of underground magazine on propagation characteristics of blast waves
Dongjoon Kim and Yoshio NAKAYAMA


For the aim of developing more efficient and higher safety for magazines, this study investigated the effect of magazine shapes on the external propagation characteristics of blast waves generated by internal explosions. The experiments were conducted by varying the internal and external volumes of the magazines. The blast wave pressures that propagated around the magazines were measured by piezoelectric sensors. The results show that overpressure of the rear direction decreases significantly as both internal and external volumes increase, whereas the front pressure varied a little.
