Based on careful analysis of variable step size gray predicted method to determine ultimate bearing capacity of single pile and interaction between soil and pile
the problems of the present model to predict ultimate bearing capacity of single pile about derivative of single pile Q-S curve and method to determine background value are pointed out. According to the law of the development on single pile Q–S curve
an improved variable step size gray predicted model to determine ultimate bearing capacity of single pile is put forward. Finally
accuracy standard and reliability of gray predicted method to determine ultimate bearing capacity of single pile are tentatively studied. By computation of the engineering example and comparing with other methods
it is shown that the model proposed is reasonable.
