The 45 Degree Rule of Thumb for Surcharges Tony& 39;s Technical

Apr 8, 20 2 The various equations we use to calculate the effect of surcharges when a surcharge will adversely affect the lateral earth pressure on retaining structures? in terms of additional loads on the shoring that supports the wall.

Overburden pressure

Overburden pressure, also called lithostatic pressure, confining pressure or vertical stress, is the pressure or stress imposed on a layer of soil or rock by the weight of overlying material. The Oxford Dictionary of Earth Sciences describes & 39;confining pressure& 39; as 'the combined hydrostatic stress and lithostatic stress; i.e. the total weight of the interstitial pore water and rock above a .

Retaining wall

Gravity walls usually must be a minimum of 50 to 60 percent as deep or thick as the height of the wall, and may have to be larger if there is a slope or surcharge on the wall. Cellular confinement systems geocells are also used for steep earth stabilization in gravity and reinforced retaining walls with geogrids.

Lateral earth pressure

earth pressure is the pressure that soil exerts in the horizontal direction. The lateral earth pressure is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations and braced excavations.
