Abstract

In this paper, the generalized-node finite element (GFE) analysis method is presented to analyze the interaction between super-long pile and soil in soft soil. A nonlinear elastic-plastic constitutive model for concrete is employed to simulate stress-strain relation of pile shaft under the axial load. The GFE model established simulates the working properties of super-long piles, and reflects well the pile-soil slide, degradation of side friction resistance and asynchronous action between side friction resistance and pile-tip resistance. The analysis method presented in this paper is suitable for analysis of super-long piles.
