What is lateral pressure in soil?
Lateral earth pressure is the pressure that soil exerts in the horizontal direction.
What is lateral earth pressure in soil mechanics and explain the different types?
Figure 15.5 shows the variation in lateral earth pressure on the y-axis as a function of the wall movement. When the wall moves away from the backfill, lateral pressure decreases with the increase in the movement of the wall; the minimum lateral earth pressure exerted on the wall is known as active earth pressure.
What is lateral pressure in civil engineering?
The pressure which acts in the horizontal direction of the soil is known as lateral pressure. It is an important factor that is considered in the design of the bridge abutment, retaining walls, basement, tunnels etc. It tries to consolidate the soil and reduce the bearing strength.
What is meant by lateral pressure?
Lateral Pressure refers to any tendency (or propensity) of individuals and societies to expand their activities and exert influence and control beyond their established boundaries, whether for economic, political, military, scientific, religious, or other purposes (Choucri and North 1972; Choucri and North 1975; Ashley …
What are the factors affecting lateral earth pressure?
The proper design of those structures required estimation of lateral earth pressure, which is a function of several factors, such as (a) type and amount of wall movement, (b) shear strength parameters of the soil, (c) unit weight of the soil, and (d) drainage conditions in the backfill.
What is earth pressure theory?
9.2 EARTH PRESSURE THEORIES Soil exerts a lateral pressure on any structure with which it is in contact. • Lateral earth pressure is the force exerted by the soil mass upon the earth retaining. structure. • The magnitude of lateral earth pressure depend on the. • Displacement of retaining structures.
What is active earth pressure in soil mechanics?
The minimum value of lateral earth pressure exerted by soil on a structure, occurring when the soil is allowed to yield sufficiently to cause its internal shearing resistance along a potential failure surface to be completely mobilized.
What is KO in geotechnical engineering?
Ko‐Coefficient of Sand in Triaxial Apparatus | Journal of Geotechnical Engineering | Vol 110, No 4.
Which assumption is true for the Rankine earth pressure theory?
Explanation: According to the assumption of Rankine’s theory, the soil mass is semi-infinite, homogeneous, dry and cohesion less.
What is active earth pressure in geotechnical engineering?
NOTE:Active and passive earth pressures are the two stages of stress in soils which are of particular interest in the design or analysis of shoring systems. Active pressure is the condition in which the earth exerts a force on a retaining system and the members tend to move toward the excavation.
