Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls , bridge abutments, seawalls , and dikes . [ 1 ] [ 2 ] Although the basic principles of MSE have been used throughout history, MSE was developed in its current form in the 1960s.
Mechanically stabilized earth, also called MSE, is soil constructed with artificial reinforcing via layered horizontal mats (geosynthetics) fixed at their ends. These mats provide added internal shear resistance beyond that of simple gravity wall structures. Other options include steel straps, also layered.
Mechanically stabilized earth (MSE) retaining walls may be used for embankments. [78] MSE walls combine a concrete leveling pad, wall facing panels, coping, soil reinforcement and select backfill. [79] A variety of designs of wall facing panels may be used. [79]
A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the ...
Typical earthworks include road construction, railway beds, causeways, dams, levees, canals, and berms.Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes.
Tiebacks to reinforce a slurry wall at Ground Zero, New York. In geotechnical engineering, a tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground.
Precast concrete retaining wall A typical cross-section of a slope used in two-dimensional analyzes. Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics to solve its engineering problems.
The walls can be curved or straight, domed with earth or topped with conventional roofs. Curved walls provide good lateral stability, forming round rooms and/or domed ceilings like an igloo . Buildings with straight walls longer than 5 m (16.4 ft) in length need intersecting walls or bracing buttresses.
