Pore Pressure Response to Probe Insertion and Thermal Gradient: ISIMU-II

Source

The ISIMU-II experiment was designed to assess the pore pressure response during piezometer and heater probe insertion and the subsequent excess pore pressure behavior as a result of a thermal field within the sediment. The dissipation of the excess pore pressures generated during probe insertion was predicted using an exponentially decreasing function which incorporates a smear factor to account for sediment remolding next to the piezometer wall. An analytical model to describe concurrently the rise in excess pore pressures as a result of sediment heating and the radial dissipation of the resulting pore pressures into the surrounding sediment is described and applied to the experimental data.
