Define the term Soil and Soil Mechanics.Write down it's importance. [2069 Poush] [2]

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.

It helps to perform engineering soil surveys.

It helps t0  develop rational sampling devices and soil sampling methods.

It helps to develop suitable soil testing equipment and soil testing methods.

It helps to investigate physical properties of soil by means of field in laboratory test.

 It helps to analyse and interpret soil test ....

Importance Of Soil Mechanics:

It helps to perform engineering soil surveys.

It helps t0  develop rational sampling devices and soil sampling methods.

It helps to develop suitable soil testing equipment and soil testing methods.

It helps to investigate physical properties of soil by means of field in laboratory test.

 It helps to analyse and interpret soil test data and classify soils.

It helps to understand the effect of various factor on soil such as static and dynamic loads, ice, water and temperature.

 solve the practical engineering problems by applying the principal of soil mechanics.
