A Novel Method for Assessing Pile Base Resistance in Sand
The base resistance of piles in sand is generally assessed through limit equilibrium-based theoretical methods. However, this approach is not capable of accounting for the punching mechanism, resulting in unconservative predictions of the ultimate load, intended as the one corresponding to a certain tolerable settlement. To overcome this issue, in this paper a novel simple analytical method for the prediction of pile tip load-settlement response is proposed. The method is mainly based on the spherical cavity expansion theory, the input soil parameters being: critical state friction angle, relative density, initial mean effective pressure and initial elastic stiffness. The reliability of the proposed method is verified against a database including 50 in-situ pile load tests performed worldwide.
