👉 Ground engineering, also known as geotechnical engineering, is a specialized field that deals with the behavior of soil and rock under various conditions and how these materials interact with structures and infrastructure. It involves assessing the physical properties of earth materials, such as strength, compressibility, permeability, and stability, to design safe and efficient foundations, slopes, retaining walls, and other earthworks. Ground engineers use laboratory tests, field investigations, and computational models to analyze soil behavior and predict how it will respond to construction activities or environmental changes. Their work ensures that structures are built on stable ground, minimizing risks of failure, settlement, or erosion, and optimizing the use of natural resources for sustainable development.
