Soil Mechanics and Foundations 3rd Edition presents the basic concepts and principles of soil mechanics and foundations in the context of basic mechanics, physics, and mathematics. It is appropriate for a single course combining introduction to soil mechanics and foundations, or for a two-course geotechnical engineering sequence. Student View Student Companion Site. About the Author Dr. The properties of soil highly depend on the process through which the soil deposits have been developed. Following are the types of soil based on the geological agents or the processes through which the soil deposits have been developed.
Glacial Soil: This type of soil is developed, transported and deposited by the actions of glaciers. These deposits consists of rocks fragments, boulders, gravels, sand, silt and clay in various proportions i. Types of Soil ii. Residual Soil: This type of soil is found on nearly flat rock surfaces were the weathering action has produced a soil with a little or no tendency to move. Residual soil also occurs when the rate of weathering is higher than the rate of removal. Alluvial Soil: The soil transported and deposited by water is called alluvial soil.
As flowing water stream or river looses velocity, it tends to deposit some of particles that it was carrying in suspension or by rolling, sliding or skipping along the river bed. Coarser or heavier particles are dropped first. Hence on the higher reaches of a river, gravel and sand are found.
However on the lower parts, silt and clay dominate where the flow velocity is almost zero or very small. Types of Soil iv.

Aeolian soil as two main types namely Dune sand and Loess. They generally occur in deserts and comprise of sand particles, which are fairly rounded and uniform in size. The particles of the dune sand are coarser than the particles of loess. Dune material is generally, a good source of sand for construction purposes.
Sand dunes fill this view of the desert in Qatar. Types of Soil b Loess: Accumulations of wind blown dust mainly siliceous silt or silty clay laid down in a loose condition is known as loess. Silt soil in arid regions have no moisture to bond the particles together and are very susceptible to the effects of wind and therefore can be carried great distances by wind storms.
An important engneering property of loess is its low density and high permeability. Saturated loess is very weak and always causes foundation problems e. Colluvial Soil: The accumulation formed by the rock fragments and soil material resulting from the mechanical weathering of rocks is known as colluvial soil. This type of soil is formed more or less in situ or as a result of trasport by gravity over a short distance. Types of Soil 2. Engineering consideration : The types of soil based on engineering consideration depend on the particle size.
Since the engineering properties of soil markedly change with the change of particle size, different names are assigned to particular ranges of particle sizes. The soil types based on MIT classification are as follows: i. They are flaky in shape and therefore have considerable surface area. These surfaces carry electrical charge, which helps in understanding the engineering properties of clay soils. In moist condition, clay becomes sticky and can be rolled into threads. Due to electrical charge, clay shows high inter- particle attraction and thus exhibits sufficient cohesion.
It has high dry strength, low erosion, low permeability, good workability under moist condition, and can be readily compacted. Also susceptible to shrinkage and swelling. Clay soils commonly have brown colour. It has high capillarity, no plasticity and very low dry strength.

Theories for stability stability Subject Category: Properties see more details of foundations and slopes slopes Subject Category: Miscellaneous see more details are developed through the upper- and lower-bound plasticity methods as well as through the classical limit equilibrium method. Although the treatment of soil mechanics is essentially theoretical, it is not highly mathematical, and soil behaviour is represented by relatively simple equations with clearly defined parameters. A short summary of the main points covered, and simple worked examples and exercises, are provided at the end of most chapters.
