Abstract:

The problem of alleviating the damaging effects of blast-induced ground shock on underground structures of the type presently contemplated for hardened missile sites is studied. This first years effort has been directed primarily toward the design and implementation of an experimental program utilizing small cylinders and several types of shock-isolation devices. The experi mental technique was developed to the point where a satisfactory level of shot-to-shot reproduci bility of effects was attained. Of the isolation devices tested, the polyurethane foam material proved to be the most effective, reducing peak accelerations relative to the unisolated model by a factor of from 5 to 10. Author
