Parametric Study of Pile Installation Using a Numerical Approach with Material Point Method

Resumo

In engineering, problems dealing with rigid structures that penetrate the ground are common. A better understanding of the installation process of these bodies can be obtained through numerical studies. Each technique has its own advantages and challenges, and the choice of the appropriate method depends on the specific geotechnical conditions. The main objective of this work is to conduct a parametric study of pile installation by impact driving using a prototype numerical model in order to analyze the behavior of these structures when penetrating the soil. This will enable the construction of more complex numerical models that simulate impact problems, such as driving a conductor casing in oil well projects or installing monopiles in the construction of wind turbines. To achieve the established objectives, the Anura3D is employed, an open source simulator based on Material Point Method (MPM). The parametric study is carried out considering a non-cohesive soil, modeled by Mohr-Coulomb. Additionally, the pile is treated as a rigid body. The parametric study conducted in this work provides valuable insights into optimizing engineering projects, enhancing its efficiency and effectiveness .
