Lateral Earth Pressure by the Program GEO Tools

Lateral earth pressure is the pressure that soil exerts in the horizontal direction. Lateral active earth pressure at a point A in the soil is equal to the effective vertical stress σ'v multiplied by a coefficient, σh= ka σ'v. If a water table is existed, a horizontal hydrostatic water pressure is considered. Lateral water pressure at a point A in the soil is the weight of water column above that point w=γwz.
