  2. Rankine theory - Wikipedia

    en.wikipedia.org/wiki/Rankine_theory

    Rankine's theory (maximum-normal stress theory), developed in 1857 by William John Macquorn Rankine, [1] is a stress field solution that predicts active and passive earth pressure. It assumes that the soil is cohesionless, the wall is frictionless, the soil-wall interface is vertical, the failure surface on which the soil moves is planar , and ...

  3. Lateral earth pressure - Wikipedia

    en.wikipedia.org/wiki/Lateral_earth_pressure

    An example of lateral earth pressure overturning a retaining wall. The lateral earth pressure is the pressure that soil exerts in the horizontal direction. It 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 ...

  4. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    The pH is measured in soil-water (1:1) and soil-salt (1:2 ) solutions. For convenience, the pH is initially measured in water and then measured in CaCl 2 {\displaystyle {\ce {CaCl2}}} . With the addition of an equal volume of 0.02 M CaCl 2 {\displaystyle {\ce {CaCl2}}} to the soil suspension that was prepared for the water pH, the final soil ...

  5. Pore water pressure - Wikipedia

    en.wikipedia.org/wiki/Pore_water_pressure

    An ISO standard, "Soil quality — Determination of pore water pressure — Tensiometer method", ISO 11276:1995, "describes methods for the determination of pore water pressure (point measurements) in unsaturated and saturated soil using tensiometers. Applicable for in situ measurements in the field and, e. g. soil cores, used in experimental ...

  6. Rankine–Hugoniot conditions - Wikipedia

    en.wikipedia.org/wiki/Rankine–Hugoniot_conditions

    where m is the mass flow rate per unit area, ρ 1 and ρ 2 are the mass density of the fluid upstream and downstream of the wave, u 1 and u 2 are the fluid velocity upstream and downstream of the wave, p 1 and p 2 are the pressures in the two regions, and h 1 and h 2 are the specific (with the sense of per unit mass) enthalpies in the two regions.

  7. Rankine half body - Wikipedia

    en.wikipedia.org/wiki/Rankine_half_body

    Schematic diagram to describe Rankine half body flow. In the field of fluid dynamics, a Rankine half body is a feature of fluid flow discovered by Scottish physicist and engineer William Rankine that is formed when a fluid source is added to a fluid undergoing potential flow. Superposition of uniform flow and source flow yields the Rankine half ...

  8. Water table - Wikipedia

    en.wikipedia.org/wiki/Water_table

    The portion above the water table is the vadose zone. It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. [2] In coarse soils, the water table settles at the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0

  9. Standard sea-level conditions - Wikipedia

    en.wikipedia.org/wiki/Standard_sea-level_conditions

    Standard sea-level conditions (SSL), [1] also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations. The term "standard sea level " is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations.
