ABSTRACT
A simplistic analysis is presented of the development and dissipation of pore pressures in a soft clay layer as an embankment is being constructed. This analysis uses a power law assumption of spatial variation of pore pressures. For one-dimensional situations parabolic isochrones have been found to be adequate but for radial flow to vertical drains a higher value of the power law exponent is required. A procedure is presented for the estimation of variation of pore pressures with time and position under the embankment: these pore pressures could be used as input to stability calculations.
