Pile loading tests of two bored piles of length 47m in soft soil are carried out for 28 days and 1 750 days after they are constructed. In-situ test shows that the ultimate bearing capacity of these two single piles increased about 30 %. The mechanism of time-effect of bearing capacity of pile is analyzed; and method of analyzing the effects of the time-effect of a pile’s bearing capacity on pile-soil interaction of pile-raft foundation is discussed with an engineering example.
