 - 1. Geotechnical Engineering is a branch of civil engineering that deals with the behavior of earth materials, such as soil, rock, and groundwater, under various conditions. It involves the design and construction of structures that interact with the ground, such as foundations, tunnels, and retaining walls. Geotechnical engineers analyze the properties of soil and rock to assess their stability, bearing capacity, and deformation characteristics. They use this information to design foundations that can support the loads of structures and ensure their safe and stable performance over time. Geotechnical Engineering plays a crucial role in ensuring the safety and durability of infrastructure projects and is essential for the successful completion of construction projects worldwide.
