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 />
