A Technique for Developing Probabilistic Properties of Earth Materials

Abstract

Ground shock calculation techniques currently used by analysts of explosive test events require deterministic input. In actuality, ground shock calculations should be treated probabilistically since the properties of earth materials and the characteristics of explosive blasts are dispersed random variables. In this report, probabilistic properties of earth materials are developed for each layer of the sub-surface profile at a given site. One-way analysis of variance tests conducted on mass volume, index, and seismic velocity data determine the profile. Probabilistic mechanical properties are based on covariance analysis of laboratory test results, field experiments, and engineering knowledge. A procedure for extrapolating the variance of laboratory based recommended probabilistic mechanical properties to higher stresses is presented. The analysis technique was applied to data obtained for two adjacent areas located near Yuma, AZ. One-way analysis of variance of mass-volume data was very useful for developing the subsurface profile.
