Geotechnical Engineering Projects book is intended for use as a supplement for geotechnical engineering and foundation engineering classes. These projects can be good samples for civil engineering students and professionals for their projects. It presents two comprehensive design projects about pier foundation and retaining wall. Problem statements are presented as real-life projects. Pier foundation design includes subsurface exploration analysis, preliminary design, settlement check, overturning check, sliding analysis, bearing capacity, and reinforcement design of foundation. Retaining wall design project contains Geogrid-Reinforcement selection, wall type selection, size of leveling pad, drainage check and CAD detailing.
