Coulomb's Earth Pressure Theory

Coulomb's Earth Pressure Theory explains how soil exerts lateral pressure on retaining structures like walls. It considers the soil's weight, friction between soil and wall, and the slope of the ground to determine the force pushing against the wall. The theory assumes a failure plane within the soil, along which the soil tends to slide. By calculating this force, engineers can design walls that safely resist soil pressure, preventing collapse. Essentially, it helps predict how much sideways force the soil will push on a structure, ensuring stability and safety.
