BEARING CHARACTERISTICS OF THE BORED PILE IN CONSIDERATION OF PILE-SOIL COMBINED ACTIONS

  • This study concerns with the C14 building, which is in Beihai, Gaizhou for fisherman's residence. Static load tests on two test piles were carried out and the Q-S curves,the lateral friction resistance vs. depth curve, the soil interface relative displacement vs. depth curve and the axial force vs. depth curve were obtained. According to the field survey data and parameters empirically selected for the finite element a single pile model. The large finite element analysis software ADINA is used to analyze the single pile, and the main bearing characteristic curves are plotted by MATLAB according to the simulation data and the measured data. The rationality of the model and the parameters are first validated, and the relationship between the pile length and the main bearing characteristics of the single pile is studied. Finally the relationship of the pile group's main load-bearing characteristics and the pile length and the pile spacing are analyzed by using the pile group model built based on the model and the parameters of the single pile.
