Soil Mechanics and Foundation Engineering: Complete Guide for Civil Engineering Students<\/h2>\n

What is Soil Mechanics?<\/strong><\/h3>\n

Soil is defined as uncemented and unconsolidated aggregate of mineral grain and decayed organic matter (solid particles) with liquid and gas in the empty spaces between the solid particles. It consists of gravel, sands, silts and clay.<\/p>\n

Soils are formed by the disintegration of rock either by physical weathering or by chemical weathering.<\/p>\n

Stages in geological cycle of soil formation are:<\/strong><\/p>\n

    \n
  1. Weathering<\/li>\n
  2. Deposition<\/li>\n
  3. Transportation<\/li>\n
  4. Upheaval<\/li>\n<\/ol>\n

    Soil Mechanics<\/strong> is the branch of science that deals with the study of physical properties of soil masses subjected to various types of forces.<\/p>\n

    Terzaghi is known as the father of soil mechanics.<\/p>\n

    According to Terzaghi (1948) soil mechanics is the application of civil engineering involving the study of soil, its behaviour and application as the engineering materials.<\/p>\n

    What is Foundation Engineering?<\/strong><\/h3>\n

    In civil engineering, a foundation is the interface between a structure and the underlying rock or soil<\/a>. The foundation should be designed in such a way that the load it transmits to the soil does not cause soil shear failure or result in excessive settlement of the structure. Foundation engineering is a branch of civil engineering that focuses on the design of foundations for buildings and other structures, as well as non-foundation problems such as the design of retaining walls, bulkheads, cofferdams, tunnels, and earth dams. It also covers the design of natural slopes, soil dewatering, and the mechanical and chemical stabilization of soils.<\/span><\/p>\n

    Importance of Soil Mechanics & Foundation Engineering<\/strong><\/h3>\n

    Apart from the testing and classification of various types of soil, in order to determine the physical properties, knowledge of soil mechanics is particularly helpful in following problems of civil engineering.<\/p>\n

      \n
    1. Foundation design of construction<\/li>\n
    2. Pavement design<\/li>\n
    3. Design of underground structures and earth retaining structures.<\/li>\n
    4. Design of embankment and excavation.<\/li>\n
    5. Design of earth dams<\/a><\/li>\n<\/ol>\n

      Foundation engineering is important in civil engineering because of the following reasons:<\/p>\n

        \n
      1. Helps in preventing failure of structure.<\/li>\n
      2. Ensures long-term stability of structure.<\/li>\n
      3. Optimizes construction cost.<\/li>\n
      4. Helps in understanding load distribution.<\/li>\n<\/ol>\n
