Dislocation Analysis of Penetration in Saturated Porous Media

Abstract

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
