This paper describes a procedure for determining the insitu coefficient of consolidation by observing the dissipation of excess pore pressures generated during piezometer probe penetration. The procedure consists of a curve matching between the computer-generated plots and the field piezometer probe dissipation plot. The computer plots are developed by means of a two-dimensional uncoupled axisymmetric consolidation dissipation of an assumed initial excess pore water pressure distribution. The initial excess pore pressure distribution, calculated using cavity expansion theory, is related to the field penetration generated pore pressures. Computations are made in an incremental manner which permits pore pressure dissipation to occur during tip penetration. The new procedure was applied in studies of three different sites and the resulting coefficients of consolidation showed reasonable agreement with laboratory-determined values.
