Underground Ammunition Storage. Blast Propagation in the Tunnel System. Report III A. Single Chamber Storage. Variable Tunnel Diameter and Variable Chamber Volume.

摘要

Model tests have been performed to determine the blast wave propagation in the tunnel system of underground single chamber storage sites. A total of nine configurations were tested with variable tunnel diameters (6,7 - 13,5 cm), chamber volumes (7250 - 15200 cc), and TNT loading densities (1 - 70 kg/cu m). Analysis of the blast wave data produced simple scaling relationships which contain a wide range of important geometrical parameters. Comparisons are given with one large scale test and the importance of wall roughness attenuation is discussed. (Author)
