Abstract:
Two numerical simulations were performed with the 2-D RAGE code to examine potential designs for a proposed seismic source test. The first calculation simulated the original design of the proposed SHIST test which was intended to demonstrate the use of near-source instrumentation developed in the HYDROPLUS program along with near-field seismic instrumentation to evaluate the seismic source function for hard rock. The calculation modeled the explosion of a 20-ton sphere 6f QM-l00R explosive buried at a depth of approximately 40 meters. The second calculation was intended to examine whether the next test in the DISTANT MOUNTAIN test series, DM4, could also be used to satisfy some of the objectives of the SHIST test. For that calculation, the 2Q-ton charge (nitromethane in this case) was placed at the ground surface in a planar array typical of the DISTANT MOUNTAIN test series. An approximate yield equivalency factor for the two charge configurations was developed from the calculations.
