soil geotechnical engineering and foundation engineering

[attachment=17763]

SOIL :

Natural aggregates of mineral grains, loose or moderately cohesive inorganic or organic in nature that have the capacity of being separated by means of simple mechanical processes.

Structures are built with soil
Dams , embankment
Structures are built in soil
Structural foundations – footings, piles, rafts, tunnels

Geotechnical engineering

A unique combination of science, experience, judgment and a passion for understanding the uniqueness and variability of ground conditions resulting from the forces of nature.

It is the art of determining the properties of unseen and variable materials to provide a facility that perform as expected at acceptable level of risk and at an optional cost.

Foundation Engineering

In a broad sense, foundation engineering is a art of selecting, designing and constructing the elements that transfer the weight of structure to the underlying soil or rock.
The role of engineer is to select the type of foundation, its design and supervision of construction.
