Abstract
Abstract A set of empirical expressions has been developed for performance assessment of underground munitions storage structures. These expressions, with the associated site characterization methodology, provide cost-effective techniques for siting, design and construction, loading density optimization, performance assessment, and risk analysis of sub-surface facilities. The developed technology uses site specific data on characteristics of the geologic and engineered systems. Using this approach, quantity–distance (Q–D) and maximum range for blast-induced hazardous fragments for accidental detonation of the magazine can be predicted. The mathematical expressions were validated in the field through a series of under 1-g explosion experiments on scaled-models of tunnels. Their applications were successfully verified through several full-scale prototype cases in the United States and Europe. This paper provides detail of the test program and steps taken to formulate and validate the empirical models. Finally, predictive capability of the models is compared with the results from full-scale magazine explosion tests.
