Introduction
Soil mechanics is a discipline that uses the principles of mechanics to describe the behaviour of soil of engineering scale. Branch of Science dealing with the structure, Engineering properties and reactions (behaviour) of soils under loading and weathering. This studies theoretically and practically soils for building of structures over it. Knowledge of physics, mechanics, and hydraulics applied to study the behaviour of soils. Also called Geo-Technique (Geo-Tech Engineering) Studies the mutual interaction of soils and structure. The practice of Engineering which applies the principles of soil mechanics to the design of engineering structures is called soil mechanics Engineering or Geotechnical Engineering.
