Description: Technical Report
Summary: Tests were made to study the effects on snow structures of surface and above-surface high explosive blasts from 4- and 32-lb. spherical cast TNT charges. A 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 a relation between surface overpressure and the ratio of arch span (S) to arch crown thickness (T). Some correlation was found for vertical arches but none between vertical and horizontal arches. The results show that, for the same charge weight and S/T ratio, the horizontal arches can withstand over 100 psi overpressure while small-scale vertical arches fail at 20-psi.
