Who is the father of soil mechanics?

Karl Terzaghi
If civil engineering were a game, Karl Terzaghi had a right to lay down the rules—he had invented and established much of the groundwork. Terzhaghi (1883-1963) is one of the leading civil engineers of the 20th century and is widely known as the father of soil mechanics.

What is types of soil mechanics?

Soil can be defined in many ways. In civil engineering, soil is a naturally occurring, loose/un-cemented/weakly cemented/relatively unconsolidated mineral particles, organic or inorganic in character, lying over the bed rock which is formed by weathering of rocks.

What are the application of soil mechanics?

Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that are buried in soils. Example applications are building and bridge foundations, retaining walls, dams, and buried pipeline systems.

What is void ratio formula?

in Parameters. Soil void ratio (e) is the ratio of the volume of voids to the volume of solids: e = (V_v) / (V_s) Where V_v is the volume of the voids (empty or filled with fluid), and V_s is the volume of solids.

What is compression index in soil mechanics?

The Compression Index (Cc) is equal to the slope of the graph of pressure versus void ratio (log scale) [7]. Compression Index (Cc) for clay is in the range 0.258 to 0.968, while for laterite soil was in the range 0.101 to 0.940. Value of Compression Index (Cc) is different between each type of soil.

What is liquid limit of soil?

Liquid limit is the water content where the soil starts to behave as a liquid. Liquid limit is measured by placing a clay sample in a standard cup and making a separation (groove) using a spatula. The cup is dropped till the separation vanishes. The water content of the soil is obtained from this sample.

What is the unit weight of soil?

The unit weight, also known as the ‘weight density’, of a soil refers to its weight per cubic metre and is typically expressed as kilonewtons per cubic metre (kN/m3), or tons per cubic metre (t/m3)1.

What is G in soil mechanics?

The specific gravity (GS) of a soil refers to the ratio of the solid particles’ unit weight to the unit weight of water.

What is compressibility of soil?

Compressibility is the degree to which a soil mass decreases in volume when supporting a load. Compressibility is lowest in coarse-grained soils where particles are in contact with each other.

What is the strength of soil?

The mechanical strength of soil is an important concept in considering (and predicting) soil behaviour. We use strength to represent the reaction of a soil to an applied force. High-strength soils resist deformation (compaction especially), break-up (shearing and shattering), and slippage.
