Soil Mechanics in Engineering Practice Lectures
Soil Mechanics Introduction and Definition
Soil mechanics is defined as the application of the laws and principles of mechanics and hydraulics to engineering problems dealing with soil as an engineering material. Soil has many different meanings, depending on the field of study. To a geotechnical engineer, soil has a much broader meaning and can include not only agronomic material, but also broken-up fragments of rock, volcanic ash, alluvium, Aeolian sand, glacial material, and any other residual or transported product of rock weathering.
As the name Soil Mechanics implies the subject is concerned with the deformation and strength of bodies of soil. It deals with the mechanical properties of the soil materials and with the application of the knowledge of these properties to engineering problems. In particular it is concerned with the interaction of structures with their foundation material. This includes both conventional structures and also structures such as earth dams, embankments and roads which are their-selves made of soil.

Constituents of Soil
Sand, Silt, Gravel, Stones
Types of Soil
The grain-size characteristics of soils that are predominantly coarse grained are evaluated by a sieve analysis
A nest of sieves is prepared by stacking sieves one above the other with the largest opening at the top followed by sieves of successively smaller openings and a catch pan at the bottom of all the sieves
There are two soil classification systems in common use for engineering purposes.
Those dams in which the dam body is made up of materials from the earth (Soil) are called earth filled dams..... [Read More]

Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio.. [Read More]

|The traditional building materials for bridges are stones, timber and steel, and more recently reinforced and pre-stressed concrete. For special elements a alloys and some types of plastics are used. These materials have different qualities of strength, workability, d ability and resistance against corrosion. They differ als eatment with differing texture... [Read More]||Collection of downloadable books and ebooks about soil mechanics, geotechnical engineering, geology & foundation engineering...
