  2. Mechanically stabilized earth - Wikipedia

    en.wikipedia.org/wiki/Mechanically_stabilized_earth

    The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing ...

  5. Retaining wall - Wikipedia

    en.wikipedia.org/wiki/Retaining_wall

    A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.

    Terraced wall on La Gomera. A terraced wall, also a terrace wall, or a terraced retaining wall is a wall that is divided into sections over a slope. Such designs are useful when building on a steep grade. Terraced walls may be built with many different materials. Some craters have terraced walls, which includes complex craters. [1] [2]

  9. 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 ...
