Based on the theory of effective stress

consolidation solution around the pile which is taken into account the influence of strain softening

magnitude of pile radius and range of excess pore water pressure

a theoretical relationship about time-effect of bearing capacity of single pile is developed

which can be used to predict the variation of shaft bearing capacity of a jacked-in pile with time in saturated soft clay. Different from the traditional way

the effect of different stiffness indices and different consolidation coefficients on the consolidation process in varied clays and highly stratified deposits are considered in the new consolidation solution. Besides

the rationality of the solution is verified by the pile load tests in different time periods after installation.
