Dilatational-wave-induced pore-water pressure in soil
Date of Original Version
This paper examines peak and residual pore-water pressures in water-saturated soil induced by a dilatational stress wave. Our new laboratory testing device applies submillisecond, high pressure dilatational stress-wave loadings to water-saturated soil. The soil's initial effective stress, density, back pressure and saturation can be controlled with our device. Experimental results show that it is possible to induced residual excess pore-water pressure and liquefaction in water-saturated Monterey No. 0/30 sand. Liquefaction is induced with compressive strains exceeding 0.1 percent for loose samples consolidated at 172 kPa and 1 percent for dense samples consolidated at 690 kPa. Below a threshold compressive strain of about 0.005 percent, no significant residual excess pore-water pressures are developed. © 1989 Society for Experimental Mechanics, Inc.
