A STUDY OF PORE AIR PRESSURES GENERATED IN SOIL SUBJECTED TO AIR SHOCK WAVES.
Abstract
The propagation of pore air pressure in specimens of soil subjected to a shock wave was investigated in two series of tests. The soils tested were a uniformly graded pea gravel, a standard 20-30 Ottawa sand, and a well-graded silty sand. The orientation of the shock wave to the soil sample was head-on in the first series of tests, and side-on in the second. In the first series, the maximum overpressure (reflected) on the upstream end of the sample was approximately 126 psi; and in the second, the maximum incident pressure was approximately 115 psi. The effect of wave shape, peak overpressure, permeability, total impulse per unit area, and positive-phase duration is ascertained. The data are also qualitatively reviewed in the light of full-scale field conditions. (Author)
