Abstract: It is important for many engineering to determine the ultimate bearing capacity of a single pile by using the data of pile field load test below limited load. A group of prediction models that can predict the capacity of a single pile are established by the gray system theory. A practical engineering example verifies that these models can meet the project requirement; moreover the self-modifying GM(1,1) model has the most high accuracy.

Key words: gray system theory, ultimate bearing capacity of a single pile, gray prediction, non-same step GM(1,1) model group
