Abstract:Using the fitting method of mathematical model and selecting Sloboda growth curve model, the fitting analysis of load-settlement curves and the prediction of vertical ultimate bearing capacity of long DX piles were carried out. The fitting results of 9 field measurement data with the model show that the fitting precision is high, the correlativity coefficients is from 0.996 49 to 0.999 68, the average value is 0.998 78. The fitting effect with the model is better than the hyperbolic model. The error between prediction value and actual measurement value is 3.937 49% ,and especially, is 1.295 31% in the tail of fitting curves. The results show that the Sloboda mathematical model have better precision for fitting of load-settlement curves, and corresponding fitting equations can be used to forecast bearing capacity of DX piles.
