Investigation of Underground Explosions with Model Tests: Measurements in the Tube

Abstract

Model tests in three scales were undertaken to examine if simple scaling laws can be used to investigate underground explosions. Charges were detonated in steel tubes, and pressures and arrival times were measured in the tube and on a platform. This report describes the results from the measurements in the tube. A systematic deviation from the scaling laws is observed. The dependence of this deviation on tube diameter, charge weight and wall roughness is examined. The results from the measurements on the platform are given in ADA062801.
