What is Geotechnical Engineering?<br />

Geotechnical Engineering is a branch of civil engineering concerned<br />

with the engineering behavior of earth materials. Geotechnical<br />

engineering is important in civil engineering, but also has applications<br />

in military, mining, petroleum, and other engineering disciplines that<br />

are concerned in construction occurring on the surface or within<br />

ground.<br />

Soil Mechanics<br />

Soil mechanics is a branch of soil physics and applied mechanics that<br />

describes the behavior of soils. It differs from fluid mechanics and solid<br />

mechanics in the sense that soils consist of a heterogeneous mixture of<br />

fluids (usually air and water) and particles (usually clay, silt, sand, and<br />

gravel) but soil may also contain organic solids and other matter.<br />

Soil mechanics is used to analyze the deformations of soil and flow of<br />

fluids within natural and man-made structures that are supported on or<br />

made of soil, or structures that are buried in soils.<br />

Foundation Engineering<br />

Foundation Engineering is<br />

the application and practice<br />

of the fundamental<br />

principles of soil mechanics<br />

and rock mechanics in the<br />

design of foundations of<br />

various structures. This<br />

foundations include those of<br />

columns and walls of<br />

buildings, bridges<br />

abutments, embankments,<br />

and others. It also involves<br />

the analysis and design of<br />

earth-retaining structures<br />

such as retaining walls,<br />

sheet-pile walls, and braced<br />

cuts. .<br />

SHALLOW FOUNDATION<br />

is a termed bases, footings,<br />

spread footings, or mats.<br />

Footing is established some<br />

distance below the ground<br />

surface for several possible<br />

reasons;<br />

• To get below weak<br />

near-surface soil<br />

• To get below the frost<br />

line<br />

• To eliminate expansive<br />

clay or the danger of<br />

scour of soil below the<br />

footing<br />

DEEP FOUNDATION<br />

Are employed principally<br />

when weak or otherwise<br />

unsuitable soil exists near the<br />

ground surface and vertical<br />

loads must be carried to<br />

strong soils at depth. It has<br />

number of uses;<br />

• To resist scour<br />

• To sustain axial loading<br />

by side resistance in<br />

strata of granular soil<br />

or competent clay<br />

• To allow above-water<br />

construction<br />

• To serve as breasting<br />

and mooring dolphins<br />

• To improve tahe<br />

stability of slopes<br />

All engineered construction<br />

resting on the earth must be<br />

carried by some kind of interfacing<br />

element called a foundation. The<br />

foundation is the part of an<br />

engineered system that transmit<br />

to, and into, the underlying soil or<br />

the rock loads supported by the<br />

foundation and its self-weight. The<br />

resulting soil-stresses-except at<br />

the ground surface-are in addition<br />

to those presently existing in the<br />

earth mass from its self-weight<br />

and geological history.<br />
