Abstract: Based on dissipation of 3-D excess pore water pressure due to static pressed pile in soft clay, consolidation of the clay around the pile and failure model of pile-soil interface, an analytical solution to estimate time-depended ultimate bearing capacity of the static pressed pile was obtained. To static pressed pile in soft clay, the presented solution shows that the ultimate bearing capacity of 50 d may reach 70 % that of the final capacity. Results from the presented solution are in agreement with site tests.

Key words: static pressed pile, excess pore water pressure, ultimate bearing capacity, time effect, interface
