Effect of explosions on snow structures
Tests were made to study effects on snow structures of surface and above-surface high explosive blasts from 4- and 32-lb spherical cast TNT charges; number of small- and full-scale vertical and full-size horizontal arches were constructed in processed snow pads; arch spans and arch crown thickness were varied to establish relation between surface over pressure and ratio of arch span (S) to arch crown thickness (T); some correlation was found for vertical arches but none between vertical and horizontal arches; results show that, for same charge weight and S/T ratio, horizontal arches can withstand over 100 psi over-pressure while small-scale vertical arches fail at 20 psi.
