SHOCK ISOLATION BY DISCONTINUITIES

Abstract

The objective of the study reported herein was to determine the effectiveness of several simple discontinuities in attenuating explosively produced ground shock. In a series of field tests, open trenches and augered holes were used to attenuate ground motion produced by small buried HE detonations. Measurements of particle acceleration obtained during the test program indicated a reduction factor of about 6 due to an intervening trench. Augered holes as discontinuities produced little or no effects until a hole spacing of 3 in. was reached. A reduction factor of about 2 was noted for this spacing.
