Abstract:

The first experiment in a series was conducted as part of a study to gain a better understanding of the behavior of the pore pressure in a soil system subjected to blast loading. In such a system, the pore pressure has a direct influence on the loading and foundation support conditions associated with buried structures. A 10-foot-high, 8-inch-diameter column of uniform, rounded Ottawa sand was loaded with dynamically pressurized air from above with the NCEL atomic blast simulator. Pore pressure and total soil pressure were monitored at various depths. Data yielded information about propagation velocity and attenuation of pore pressure and effective soil stress. Author
