  Soil mechanics Summary
Soil mechanics is an important discipline for many branches of engineering, such as Civil engineering, Geotechnical engineering and Engineering geology.
The shear strength is related to the soil type, thus, the response of a granular soil to an applied load depends to a large extent on its density, whereas a cohesive overconsolidated soil exhibits a markedly different behaviour to that of a pond.
Ultimate bearing capacity of soil is the value of the average contact pressure between the foundation and the soil which will produce shear failure in the soil.

 Soil & Rock Mechanics
The soil index properties are used extensively by engineers to discriminate between the different types of soils within broad categories.
Soil shear strength parameters are important for stability as every physical structure will impose some load on the soil that supports the foundations.
The data from this test together with classification data and the knowledge of the soils loading history enable estimates to be made of the behaviour of the foundation under load.

Soil mechanics is the study of the behaviour of the ground when mechanical loads are applied to it or fluid flows through it.
All soil consists of a collection of gravel, sand, silt or clay particles with varying spaces between them which are usually filled with water.
Soil behaviour is not only dependent on these past unknown loads, it is really governed by the way the individual (and infinitely varied) sand or clay particles which make up the soil interact with one another.
