Effects of a shock wave on a Peter snow arch : preliminary report
McCoy, John E.; Waterhouse, Robert W.
Special ReportSummary: During July 1959, the U. S. Army Snow Ice and Permafrost Research Establishment (USA SIPRE) was requested by the Office, Chief of Engineers to conduct a small-scale test to evaluate the resistance of a rigid snow trench cover to the blast effects of a military explosive. The USA SIPRE field crew conducting research on snow structures at Camp Century, 138 miles inland from Camp Tuto, Greenland, was requested to prepare the test setup. U. S. Army Engineer Waterways Experiment Station (USA WES) was requested to measure the magnitude of the pressure wave during the test. The objective of the test was to obtain preliminary information which would be used to estimate the probable effect of large-scale explosions on a snow arch roof. This test indicated that a fully age-strengthened Peter-snow arched trench cover of 9 ft span and 24 in. thickness at the crown could resist a 15 psi blast overpressure.
