    Abstract:

    In order to promote the application of the reverse self-balanced pile test method in the practice engineering, the numerical simulation analysis of the reversed self-balanced pile test method is carried out by using the finite element analysis method. Taking the pipe pile as an example, the numerical model of reverse self-balanced test pile method is established by the ABAQUS software. The displacement control method and load control method are used to simulate the loading of pile body and pile top, and the ultimate compressive bearing capacity of the foundation pile is obtained, from which the pile axial force and the pile lateral friction resistance can be analyzed. The established numerical model is modeled by the static load test with the displacement control method and compared with the ultimate bearing capacity simulated by the reverse self-balance test method. The simulation results show that the ultimate bearing capacity of foundation pile determined by the reverse self-balance test method is relatively close to the result of the static load test method, and the conversion of positive and negative friction resistance is not necessary, but there is also the problem of determining the position of the balance point.
