Quantification of Rock Damage from Small Explosions and its Effect on Shear-Wave Generation: Phase I - Homogeneous Crystalline Rock; Conference paper

摘要

We are currently conducting a one-year feasibility study to determine the most efficient way to characterize the damage from an explosive source and to identity the source(s) of shear wave generation. We hope to quantify crack nucleation and growth (Ashby and Sammis, 1990) as an S-wave generation mechanism in the far-field (Sammis, 2002) and to map the cone of damage (Patton et. al. 2005; Stevens et. al. 2003) above a source, modeled by a compensated linear vector dipole (CLVD). This study is being conducted at a quarry in Barre, Vermont, in a granite body that has a low fracture density and typically forms large blocks used for monuments. In this study, we are detonating five small.
