Theoretical Analysis and Numerical Simulation Research on the Bearing Capacity of Variable Cross-section Piles
The ABAQUS finite element analysis software is used to analyse the characteristics of the bearing capacity and the internal forces of the variable cross-section piles and the vertical load transfer mechanism of the pile top.The variable section pile can transfer the load of the pile top to a deeper soil layer.The side friction resistance is maximized and the utilization of the bearing capacity of the pile is significantly improved.The end resistance of the pile section is played in advance and more fully,and the side resistance en-hancement effect is generated,and the side friction resistance near the variable section can be played to a greater extent.
