The Development of Reciprocity Procedures for Utilizing Data from Underground Explosion Tests

Abstract

A procedure for predicting underground cavity motions resulting from surface air-blast loading is developed on the basis of a dynamic-reciprocity principle for a nonhomogeneous, anisotropic, linear, viscoelastic half space. A computer program for evaluating the integral equations for this medium is presented. Experimental measurements from the RAINIER event of operation PLUMBBOB are used to postulate cavity motions arising from a surface burst at the RAINIER site. The effects of variations in the cavity pressure signature, number of measure ground motions, and instrumentation errors are examined. Recommendations are made for experimental programs to obtain needed additional data, and, in general, to ascertain the applicability of the reciprocity to soils.
