Nonlinear Method for Load Transfer Model of Super-Long Pile in Layered Soil
In this paper, a three-stage softening load transfer model, based on existing experimental data of super-long piles, is proposed; the hyperbola load transfer model is adopted to simulate the nonlinear deformation of pile-tip soil; and the elastic-plastic model of concrete is introduced, giving consideration to the super-long pile shaft deformation under heavy axial loads. Then the models above are implemented into pile-soil load transfer differential equation, and after being solved by iteration method, the nonlinear method for load transfer model of super-long pile in layered soil is established. After that programming of the model calculation is worked out. By comparison with engineering instance, it is shown that the method proposed in this paper is convenient and reliable in engineering practice.
