Pile installation induces significant changes in soil state around the pile, affecting its stiffness and bearing capacity. Understanding of these installation effects is crucial not only for optimising design but also for minimising the risks of potential failures. Advanced numerical techniques offer better predictions of the installation effects, addressing challenges posed by the complex (dynamic) large deformations in the soil around the pile and the mechanical behaviour of soil under complex loading conditions during installation. This presentation focuses on the development of the material point method (MPM) to simulate various installation techniques commonly used in practice. It builds upon the previous studies of the authors, which include simulations of monotonic and cyclic cone penetration tests (CPT), impact-driven piles, vibratory-driven piles, gentle-driving piles, and suction caissons.
