Numerical Modeling for Geoengineering

To provide students with the theoretical and practical knowledge required for the advanced analysis of applied geology and geotechnical engineering problems using numerical modelling—an essential tool when the complexity or significance of the problem makes traditional analytical or semi-empirical solutions inadequate.

Numerical modeling represents the tool through which a complex geotechnical problem can be analyzed, allowing the simulation of evolving scenarios in response to multiple variables. The theoretical approaches implemented in dedicated software vary and must be selected according to the specific nature of the problem.

The student will be able to transition from the conceptual model describing the problem (e.g., landslides, small- and large-scale geo-engineering works, etc.) to the geotechnical model, select the most appropriate numerical approach, and carry it out using dedicated software tools.

In particular, the main expected outcomes are as follows:

· Understand the governing field equations of geo-engineering problems describing the hydro-mechanical behavior of soils and rock masses, with particular focus on the most widely used constitutive models for geomaterials.

· Understand the functioning of numerical codes suitable for geo-engineering analysis, with specific reference to the finite element and discrete element methods.

· Be able to consciously use a numerical code, addressing the problem from the domain definition and initial and boundary conditions to the selection of physical and hydro-mechanical parameters.

· Be able to tackle, through numerical modeling, a range of practical problems commonly encountered in applied geology and geotechnics, such as slope stability in soil or rock, slope stabilization through drainage and/or structural works, and the assessment of settlements and subsidence.

· Understand the principles and application domains of more innovative and environmentally sustainable interventions, such as low-enthalpy geothermal installations (energy geostructures).
