Pullout resistance of rigid composite piles based on finite element method
To further predict the vertical pullout resistance of rigid composite piles and reduce construction costs,pullout test was conducted on rigid composite piles.Based on the results of field tests,a comparison was made with finite element simulation results to analyze the variation patterns of pullout resistance of rigid com-posite piles under different pile lengths and diameters during the loading process.The results showed that com-pared to the field test results,the maximum displacement error rate of the simulated load-displacement curve of rigid composite piles was about 13%;under the maximum load,as the pile length increased,the displacement at the pile top gradually decreased,and the main stress position of the pile body deepened;for every 200 mm increase in pile diameter,the pile top displacement decreased by about 9%,and the main stress position of the pile body gradually moved upward.Therefore,increasing the pile length and diameter can improve pullout re-sistance of the pile to a certain extent.
