Abstract:
Based on gray model in the realization of MATLAB, three piles of experimental data are investigated as object, the residual data from different number of experiment groups are analyzed by using the ideal model of metabolism which is one of the gray models. Compared the different groups of residual value, we can figure out the best experiment data to predict the uplift bearing capacity. At the same time, a method to predict the ultimate bearing capacity are proposed through the hyperbolic model to the optimal forecast data of each pile in piece-wise linear fitting, analysis the relationships? between linear fitting and ultimate capacity, we can finally get the recommended value of ultimate bearing capacity of each pile.
