Coulomb’s Theory for Earth Pressure | Soil - Soil Management India
Coulomb (1776) developed the wedge theory for determination of lateral earth pressure on a retaining wall. Unlike Rankine’s theory, which considers the equilibrium of a soil element, Coulomb’s theory considers the equilibrium of a sliding wedge of soil in the backfill that separates from the rest of the backfill above a … 展开
Figure 15.51(a) shows a retaining wall of height H, with a cohesive backfill, with its surface inclined at angle β with the horizontal. The back of the wall is inclined at an … 展开
As per Coulomb’s theory, a wedge of soil above a failure plane moves inward and upward in the passive case when the wall moves toward the soil on the front side of the … 展开
