lateral earth pressure

The equations for active and passive lateral earth pressure coefficients are given below.

These equations represent the total lateral earth pressure.

Coulomb (1776) first studied the problem of lateral earth pressures on retaining structures.

Soil mechanics; most notably in lateral earth pressure theory and the stabilization of retaining walls.

Lateral earth pressure coefficients are broken up into three categories: at-rest, active, and passive.

Lateral earth pressures are addressed elsewhere.

Lateral earth pressure is the pressure that soil exerts against a structure in a sideways, mainly horizontal direction.

At rest lateral earth pressure, represented as K, is the in situ lateral pressure.

There are many theories for predicting lateral earth pressure; some are empirically based, and some are analytically derived.

Lateral earth pressures are zero at the top of the wall and - in homogenous ground - increase proportionally to a maximum value at the lowest depth.

The article concludes with some examples of applications of the principles of soil mechanics such as slope stability, lateral earth pressure on retaining walls, and bearing capacity of foundations.

These lateral loads are usually wind and earthquake loads, but other lateral loads such as lateral earth pressure or hydrostatic pressure can also be resisted by diaphragm action.

The common applications of lateral earth pressure theory are for the design of ground engineering structures such as retaining walls, basements, tunnels, and to determine the friction on the sides of deep foundations.

The consultant's report concluded that evidence suggested the pier underwent many years, perhaps 50, of creep deflection due to sustained lateral earth pressure at the foundation which was held in check by the bearing assemblies.

This creates lateral earth pressure behind the wall which depends on the angle of internal friction (phi) and the cohesive strength (c) of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes.
