Geotechnical Engineering finds solutions to problems involving soils and rock. It embraces the topics of soil mechanics, rock mechanics and foundation design. The mechanics of soils and rocks develops the bases for studying the interaction between the geological environment and man-made constructions whose large majority rest on, or below ground surface. The geotechnical engineer determines and designs the type of foundations, earthworks, and/or pavement subgrades required for the intended man-made structures to be built. Faculty at the Case School of Engineering are engage in research that examines new design in off-shore wind turbine foundations and soil mechanics for lunar missions and to name a few.
