Abstract: Time and depth were adopted to analyze excess pore water pressure (EPWP) due to driven pile in soft clay; and a 3D analytical formula was derived. Principle of EPWP dissipation process was discussed. Position and time that Mandol effect of the soil around the pile happened were analyzed. A model to calculate EPWP due to pile groups was established: during piles driving, EPWP in soil accumulates and dissipates; after that, EPWP dissipates only. And effects of pile spacing and driving order of pile group on EPWP were analyzed.

Key words: pile driving, excess pore water pressure, time effect, 3-D analytical formula, driving order of pile group
