Abstract:

The investigation of the effects of underground explosions is complicated by the wide variety of materials in which the effects of such explosions are of interest. In an attempt to avoid the necessity of extensive field tests in a large number of earth materials some of the problems concerned with the propagation of explosion-generated seismic waves in solid media were investigated on a laboratory scale using the techniques of model seismology. Of interest were the velocity, amplitude and frequency of seismic waves in various media, since from these data the elastic constants of the medium and the attenuation occurring within the medium can be calculated. A two-dimensional model is described which provided the means to study, on a scale basis, the propagation of ground shock phenomena resulting from impulsive loading such as that arising from the detonation of explosives in the ground.
