The pressure of the water exerted in a soil
WebbExplanation: (i) Soil has a tendency to exert a lateral pressure against any object in contact. (ii) Soil exerts a push against the retaining wall by virtue of its tendency to slip laterally and seek its natural slope or angle of repose. Thus making the wall to move slightly away from the backfilled soil mass. WebbThe hydrostatic pressure exerted at any point in a soil mass is known as pore water pressure. We know that the hydrostatic pressure, that is, pore water pressure at point P is given by – u = γ w h 2 … (7.4) ADVERTISEMENTS: Pore water pressure is also known as a neutral pressure and denoted by the symbol u. Its units are kgf/cm 2, t/m 2, or kN/m 2.

The pressure is positive when a soil is fully saturated, and is then proportional to the height of the water measured in an open tube (a piezometer) above the point of interest. A buoyancy effect is achieved and the shear strength of the soil is reduced. The pressure is zero …
