Design, Evaluation, and Construction of TEXESS and LUXESS and Research in Mini-Array Technology and Use of Data From Single Stations and Sparse Networks: Phase 5

摘要

In a descrimination study corollary to the AR method, phase matched filteringtechniques were used to analyze Rg dispersion from mine blasts. Short period surface waves from chemical explosions were used to obtain reliable dispersion curves for surface waves being generated, and to establish any azimuthal variations in relative Rg (fundamental-mode, short-period Rayleigh wave) energy at azimuths around the quarry, including the quarry pit's influence on these energy variations. Observed dispersion curves were interpreted using theoretical dispersion curves that consider estimated values of Poisson's ratio (0.35-0.4) for the central Texas' upper crust.
