Lateral earth pressure

It may be defined as

Lateral forces that act between the retaining structures and the soil masses being retained are caused by the pressure known as Lateral earth pressure.

Retaining structures such as retaining walls, basement walls, and bulkheads are commonly encountered. Proper design and construction of these structures require a knowledge of lateral earth pressure.

It can also be defined as

The pressure which is imparted by soils onto vertical or near-vertical structures.

It may include normal and shear pressures. Lateral earth pressure are the direct result of horizontal stresses in the soil.

Coefficient of lateral earth pressure, K

It may be defined as

The ratio of horizontal effective stress to the vertical effective stress at any point in a soil .
