Soil mechanics and foundation Engineering its application

Soil mechanics and foundation  Engineering, soil mechanics or geotechnique is one of the youngest disciplines of civil engineering involving the study of soil, its behaviour and application as an engineering material. The term ‘Soil Engineering’ is currently used to cover a much wider scope implying that it is a practical science rather than a purely fundamental or mathematical one. Good soil engineering embodies the use of the best practices in exploration, testing, design and construction control, in addition to the basic idealised theories. The field of Soil Mechanics and foundation is very vast. The civil engineer has many diverse and important encounters with soil. Apart from testing and classification of various types of soils in order to know its physical properties, the knowledge of soil mechanics and foundation  is particularly helpful in the designs of foundations, rigid and flexible pavements, underground and earth retaining structures, embankments, and excavations, and earth dams

Soil as a three phase system

A soil  as a three phase system consisting of solid particles (called soil grains), water and air. The void space between the soil grains is filled partly with water and partly with air. However, if we take a dry soil mass, the voids are filled with air only. In case of a perfectly saturated soil, …

the term soil

The Term Soil

The Term Soil The term ‘Soil’ has various meanings, depending upon the general professional field in which it is being considered. To an agriculturist, soil is the substance existing on the earth’s surface, which grows and develops plant life. To the geologist also, soil is the material in the relatively thin surface zone within which …
