  2. Dilatancy (granular material) - Wikipedia

    en.wikipedia.org/wiki/Dilatancy_(granular_material)

    Dilatancy of a sample of dense sand in simple shear. The phenomenon of dilatancy can be observed in a drained simple shear test on a sample of dense sand. In the initial stage of deformation, the volumetric strain decreases as the shear strain increases. But as the stress approaches its peak value, the volumetric strain starts to increase.

  3. Piling - Wikipedia

    en.wikipedia.org/wiki/Piling

    The typical construction process for a wind turbine subsea monopile foundation in sand includes driving a large hollow steel pile, of some 4 m in diameter with approximately 50mm thick walls, some 25 m deep into the seabed, through a 0.5 m layer of larger stone and gravel to minimize erosion around the pile.

  4. Angle of repose - Wikipedia

    en.wikipedia.org/wiki/Angle_of_repose

    When bulk granular materials are poured onto a horizontal surface, a conical pile forms. The internal angle between the surface of the pile and the horizontal surface is known as the angle of repose and is related to the density, surface area and shapes of the particles, and the coefficient of friction of the material. Material with a low angle ...

  5. Land reclamation - Wikipedia

    en.wikipedia.org/wiki/Land_reclamation

    In Ancient Egypt, the rulers of the Twelfth Dynasty (c. 2000–1800 BC) undertook a far-sighted land reclamation scheme to increase agricultural output. They constructed levees and canals to connect the Faiyum with the Bahr Yussef waterway, diverting water that would have flowed into Lake Moeris and causing gradual evaporation around the lake's edges, creating new farmland from the reclaimed land.

  6. Soil compaction (agriculture) - Wikipedia

    en.wikipedia.org/wiki/Soil_compaction_(agriculture)

    Soil compaction causes reductions in crop growth, yield and quality. Locally, these effects may have minor impacts on food security. If one aggregates the losses in food supply due to soil compaction, however, compaction may threaten food security. This is especially relevant for regions that are prone to droughts and floodings.

  8. Soil stabilization - Wikipedia

    en.wikipedia.org/wiki/Soil_stabilization

    This method uses a small, penny-sized injection probe and minimizes debris and is ideal for re-compaction and consolidation of weak soil strata, increasing and improving load-bearing capacity under structures, and the remediation of shallow and deep sinkhole problems.

  9. Soil consolidation - Wikipedia

    en.wikipedia.org/wiki/Soil_consolidation

    The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...
