A non-linear three-dimensional pile–soil model for vibratory pile installation in layered media

This paper presents a computationally efficient model for vibratory pile installation. A semi-analytical finite element (SAFE) thin cylindrical shells is derived to represent the pile. The linear dynamic response of soil medium described by means Green’s functions via Thin-Layer Method (TLM) coupled with Perfectly Matched Layers (PMLs) account underlying elastic half-space. Furthermore, non-linear pile–soil interaction addressed through history-dependent frictional interface and visco-elasto-plastic tip reaction that can be characterized on basis standard geotechnical in-situ measurements. solution problem based sequential application Harmonic Balance (HBM). constituent components are first benchmarked against established numerical schemes. Subsequently, predictions compared experimental data collected from field tests. It demonstrated proposed amalgamates rigorous theoretical elements promising prediction capabilities in framework, applicable engineering practice.
