Lateral Earth Pressure
The purpose of a retaining wall is to provide for an abrupt change in grade as required by architectural or engineering considerations. In order for this to be accomplished the retaining wall must restrain the lateral pressure exerted by the earth situated in back of the wall. A retaining wall cannot be properly designed until the designer has a clear understanding of the physical properties and in-place characteristics of the earth whose pressure the wall is to restrain. The purpose of this section is to develop the equations from which reasonable earth pressures can be computed.
