Define Soil

Soil is defined as the uncemented aggregate of minerals grain and decayed organic matter i.e, solid particles with liquid and gas in the empty spaces between the solid particles.
Soil mechanics is defined as the application of laws of mechanics and hydraulics to the engineering problems dealing with sediment and other unconsolidated accumulation of solid particles produced by the mechanical and chemical disintegration of rocks regardless of whether or not they contain an admixtures of organic constituents. This definition was given by Terzaghi,father of soil mechanics.
Geotechnical engineering is the sub discipline of civil engineering that involves natural material found close to the surface of the earth. It includes the application of the principle of soil mechanics and rock Mechanics to the design of foundations, retaining structures and Earth structures.

Purposes of soil mechanics:

The purpose of soil mechanics is to study soil on a scientific basis. Soil Mechanics supplements/replaces/modifies the empirical method of design applied in Foundation Engineering by scientific methods.
