  • Compared with traditional methods, O-cell test has unique advantages for some special sites, especially in the offshore pile foundation testing. To study the load transfer characteristics of the O-cell method for testing piles in coastal soft soil foundation, and analyze the influence of pile parameters on the conversion coefficient, this paper established the pile-soil numerical model to simulate the O-cell and traditional pile testing processes. The finite element method and equal displacement method were combined to calculate the conversion coefficient and ultimate bearing capacity, and the influence of pile parameters on the conversion coefficient was discussed. The research results indicate that the error between the equivalent conversion ultimate bearing capacity calculated by introducing the equal displacement method into the O-cell pile-soil model and the calculation results of the surcharge method is within 0.5%, and the O-cell conversion coefficient can be accurately calculated. The increase of the length and diameter of the pipe pile will significantly improve the bearing capacity of the pile foundation, and the pile parameters have a significant impact on the O-cell conversion coefficient and the ultimate bearing capacity of the pile foundation.
