Geotechnical analysis is the study of soil and rock properties to assess their behavior under various conditions. This analysis is crucial for construction projects, as it helps engineers understand how the ground will support structures like buildings, bridges, and roads. By examining factors such as soil composition, strength, and stability, professionals can make informed decisions about design and safety. The process often involves field tests, laboratory experiments, and computer simulations. Key aspects include soil mechanics, foundation design, and earthquake engineering. Ultimately, geotechnical analysis ensures that structures are built on solid ground, minimizing risks and enhancing durability.
