Pore Pressure Dissipation After Cone Penetration

M. M. Baligh / J. N. Levadoux

Deep quasi-static cone penetration in saturated soils develops excess pore pressures. This report estimates the consolidation and permeability characteristics of fine grained soils from measurements of the pore pressure decay that takes place after cone penetration is interrupted. Relatively new conical piezometers with a very rapid response time are described. Linear consolidation analyses are performed to investigate the importance of different factors affecting pore pressure dissipation around cones: initial distribution of excess pore pressures, cone angle and location of the porous stone, soil anisotropy and coupling between pore pressures and total stresses.
