Geomechanics is the study of the behavior of geological materials, such as soil and rock, under various conditions. It combines principles from geology, engineering, and mechanics to understand how these materials respond to forces, pressure, and environmental changes. This field is essential for construction, mining, and environmental projects, ensuring stability and safety. The applications of geomechanics include analyzing landslides, designing foundations for buildings, and assessing the stability of slopes and tunnels. By understanding the physical properties and behavior of earth materials, engineers can make informed decisions to mitigate risks and enhance the performance of structures built on or within the ground.
