? Soil Mechanics is defined as the branch of engineering 
science which enables an engineer to know 
theoretically or experimentally the behavior of soil 
under the action of ;
1. Loads (static or dynamic), 
2. Gravitational forces, 
3. Water and,
4. Temperature. 
? Simply speaking it is the knowledge of engineering 
science , which deals with properties, behavior and 
performance of soil as a construction material or 
foundation support.

? Terzaghi, a famous scientist defines soil mechanics 
as follows, Soil Mechanics is the application of 
Laws of  Hydraulics and Mechanics to 
engineering problem dealing with sediments and 
other unconsolidated accumulations of solid 
particles produced by Mechanical and Chemical 
Disintegration of rocks.

? With the recent advances in the science of 
Engineering, the design and execution of large 
projects, which at times were considered beyond 
imagination and control, have now become quite 
common. Sky scrapers, subways, maritime and off 
shore structures, dams and bridges spanning the sea 
are some examples of large projects.
? For the design and construction of almost all such 
projects the engineers have to deal with both soil and 
rock, either as construction material or as a 
foundation support.
