Solution is presented for the fluid-pressure response surrounding insertion of a continuous, moving point dislocation within an initially saturated porous- elastic medium. Included in the presentation is a unified framework for the analysis of penetration-generated pore pressures in soils for partially drained states and an exposition of the overt penetration rate dependence of pore-pressure generation and dissipation. Scaling parameters for data reduction are returned as a natural consequence. The analysis allows rational determination of permeability and consolidation coefficients in situ. Postarrest pore-pressure dissipation at the tip enables Cv to be determined independently. Nonuniqueness in pore-pressure dissipation along the shaft precludes independent determination of consolidation behavior.
