Nonlinear analysis of the response of a single pile subjected to tension load using a hyperbolic model

摘要

Prediction of uplift pile response is an interesting area of research in the field of geotechnical engineering. In the present approach, a hyperbolic model is adopted to simulate the relationship between pile displacement and unit skin friction developed at the pile-soil interface. Based on the hyperbolic model, a simple analytical approach is proposed to analyse the nonlinear response of a single pile subjected to tension load. Furthermore, comparisons of the results derived from the present method, other analytical methods and well-documented field experimental pile loading cases are made to demonstrate the effectiveness and accuracy of the proposed analytical methods. The proposed simple analytical approach is economical and efficient, and suitable for the analysis of a tension pile embedded into layered soils using a hyperbolic model.
