- Abstract
- Procedures used to design large-scale earthquake ground motion simulations using high explosives are investigated. Results of finite difference wave propagation calculations are combined with previous results to better define the ground motion environment as a function of explosive array height and homogeneous site material properties. Further improvement is achieved through development of a technique by which shock response spectra, for both simulation and prototype earthquakes, may be estimated. The results of these analyses are used to synthesize data from the recent SIMQUAKE events. These events employed explosive arrays to expose large-scale structural models to an earthquake-like environment. Predictions and actual large-scale test data are compared and adjustments to and verifications of the phenomenology are made. The ability to predict the ground motion environment during such tests is thus improved.
