The grounds of modeling of filling pile static resistance have been offered so as the results of its realization at the laboratory models. The laboratory testing data are compared with the data of field testing of natural piles. The experimental and the model calculated values of bearing capacity shows the correlation coef-ficient 0,692. The laboratory tests confirm the exis-tence of the local maximum of the settlement “accele-ration”. The point of maximum proposed separates two stages of bearing capacity increment process: the stage of lateral surface mainly resistance and the stage of pile bottom mainly resistance
