Soil Mechanics And Foundation Engineering

Soil Mechanics is the study of soil, its behaviour, and its use as a construction material.

Karl Terzaghi, known as the “Father of Soil Mechanics,” was born in 1948. Karl Terzaghi defined soil Mechanics as “The application of laws of mechanics and hydraulics to engineering problems dealing with sediments and other unconsolidated accumulations of solid particles produced by the mechanical and chemical disintegration of rocks, regardless of whether or not they contain an admixture of organic constituents,”.


What is soil and how is it formed?

The un-aggregated or un-cemented deposits of mineral and/or organic particles or fragments that cover a large portion of the earth’s crust are known as soil.


Weathering of rocks produces soil.

Soil Classification

On the basis of the grain size of the soil particles. Read more about types of soils by clicking here.

  • Gravel: particles larger than 2 mm, but smaller than 63 mm as gravel. The particles larger than 63 mm are denoted as stones.
  • Sand: particles smaller than 2 mm, but larger than 0.063 mm.
  • Silt: particles smaller than 0.063 mm and larger than 0.002 mm
  • Clay or Luthum: particles smaller than 0.002 mm,
