Analysis on Time Limitation of the Ultimate Bearing Capacity of Jacked Pile

The ultimate bearing capacity of jacked pile increases with the time in hyperbolically pattern. The mechanism of time effect can be interpreted as the effect of disturb-restore property and the effect of consolidation of the soil around the pile. Time is adopted to analyze excess pore water pressure due to driven pile in clay; and a formula is derived. According to the original construction force and considering fuzzy and uncertain, we can calculate the final bearing capacity of the pile. Acalculating method is given.
