Investigation of Underground Explosions with Model Tests. Measurements on the Platform

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. The objective of the tests is described in more detail in AD-A062 800, which also describes the results from the measurements in the tube. This report describes the results from the measurements on the platform. As for the measurements in the tube, a deviation from the simple scaling laws is observed. The dependence of the pressure on tube diameter, charge weight and wall roughness is examined.
