Model Tests of Accidental Explosions in Underground Ammunition Storage II:Blast Wave Propagation in Tunnel Systems.

摘要

In a previous paper measurements were reported on chamber pressure in connection with model tests of accidental explosions in underground ammunition storage sites. The present paper deals with the problem of blast wave propagation from the storage chamber down the main passage-way for some typical layouts of underground sites. The use of the present model tests in the design of underground ammunition storage sites is made possible by three special circumstances: First, the models used in the tests were designed to represent a wide range of typical full scale sites. Second, the models were carefully constructed to have sufficient strength for relatively high loading densities to cover a wide range of full scale cases. Third, parts of the tests were designed to check the validity of scaling both by comparing the results from geometrically similar models and comparisons with large scale tests.
