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 />
