Measurements and Calculations of Shock Propagation in Dry Desert Alluvium

  • Robert C. Bass

Abstract

Data obtained on shock propagation from underground explosive detonations are often “contaminated” at larger distances by surface reflections and spall signals. This is a result of the usual placement of instrumentation vertically above the detonation point in a single satellite hole; the use of multiple satellite holes that would permit measurement near the detonation horizon being prohibitively expensive. A recent underground nuclear detonation in alluvium utilized a large diameter device emplacement hole and the entire instrumentation array was installed in the backfill material. No significant spall or surface reflections were noted in the data obtained in this large cased hole and the shock structure was clearly detailed to locations close to the surface.
