Based on the elasto-plastic solution to the cavity expansion for jacked piles problems in natural saturated clay, an analytical solution to the excess pore water dissipation around the pile is derived with aid of the stress state of the soil immediately after pile installation. On this basis, a theoretical method for calculating the time-dependent bearing capacity of the jacked pile in natural saturated soil is presented by considering the soil relaxation effects on the soil around the pile during reconsoli...
