Soil Mechanics

Soil mechanics is a branch of Soil mechanics is a branch of engineering mechanics that that

describes the mechanics and physical properties of describes the mechanics and physical properties of soils. .

It utilizes the basic principles of solid mechanics, fluid mechanics It utilizes the basic principles of solid mechanics, fluid mechanics

and dynamic theories to describe the engineering behaviors of soil and dynamic theories to describe the engineering behaviors of soil

under various loading conditions.under various loading conditions.

It differs from fluid mechanics and solid mechanics in the sense It differs from fluid mechanics and solid mechanics in the sense

that soils consist of a heterogeneous mixture of fluids (usually air that soils consist of a heterogeneous mixture of fluids (usually air

and water) and particles (usually and water) and particles (usually clay, silt, sand, and gravel) but , silt, sand, and gravel) but

soil may also contain organic solids, liquids, and gasses and other soil may also contain organic solids, liquids, and gasses and other

Geotechnical Engineering

Geotechnical engineering is the branch of civil engineering Geotechnical engineering is the branch of civil engineering

concerned with the engineering behavior of earth materials (i.e., concerned with the engineering behavior of earth materials (i.e.,

soil and rock).soil and rock).

Geotechnical engineering uses principles of soil mechanics and Geotechnical engineering uses principles of soil mechanics and

rock mechanics to investigate subsurface conditions and rock mechanics to investigate subsurface conditions and

materials; determine the relevant physical/mechanical and materials; determine the relevant physical/mechanical and

chemical properties of these materials; construct in or on the chemical properties of these materials; construct in or on the

ground (e.g. foundations, man-made slopes, tunnels, etc.)ground (e.g. foundations, man-made slopes, tunnels, etc.)

Geotechnical Engineering

Geotechnical engineering is probably the most challenging Geotechnical engineering is probably the most challenging

discipline among other the disciplines of civil engineering. This is discipline among other the disciplines of civil engineering. This is

basically due to the unpredictable nature of the material it deals basically due to the unpredictable nature of the material it deals

with. Soil and rock, unlike steel or concrete, both are with. Soil and rock, unlike steel or concrete, both are anisotropicanisotropic
