XIA Jian-zhong, LUO Zhan-you, ZHANG Shi-zou. Time effect analyses and prediction of ultimate bearing
capacity of jacked pile in clay[J]. 2006, 27(S1).DOI:
Influential factors of the ultimate bearing capacity of jacked pile in clay are discussed. The relationship between the ultimate bearing capacity of jacked pile and time is analyzed. Based on the gray system theory
the gray Verhulst prediction model is proposed. Then the ultimate bearing capacity of pile is predicted by the model. The results show that the regularity of predicted ultimate bearing capacity is agreement with the measured ones; and error between predicted and measured value is small. So the gray verhulst prediction model can be applied to the practical engineering.
