Soil Mechanism

Soil mechanics is the branch of soil physics and engineering mechanics that describes the behavior of soils. It differs from solid mechanics and fluid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually like air and water) and particles (usually like clay, silt, sand, and gravel) but soil may also contain organic solids and other matter. Along with soil mechanics, rock mechanics provides the theoretical basis for analysis in geotechnical engineering a sub discipline of engineering geology and civil engineering, a sub discipline of geology. It is used to analyze the deformations and flow of fluids within natural and man-made structures that are supported made of soil, or structures that are buried in soils. Example applications are building and bridge foundations, dams, retaining walls, and buried pipeline systems. Principles of soil mechanics are also used in related disciplines such as geophysical engineering, engineering geology, coastal engineering, agricultural engineering, soil physics and hydrology.
