Abstract:

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 kgcu 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.
