ABSTRACT
An experimental investigation of impact loading of buried structures has been conducted in two series of experiments. Models were tested in a laboratory floor apparatus in the first series and at elevated gravity in a geotechnical centrifuge in the second. In each case the model consisted of a flexible cylinder located in a medium of sand. The impulsive loading of the soil/structure system was provided by a mass impacting on a plate located at the surface of the soil immediately above the structure. Instrumentation in the soil and of the structure permitted monitoring of the propagation of the P-wave and the structural response. The results of the experiments are compared with predictions of stress wave attenuation and dynamic magnification factor.
