cohesionless

The movement of a cohesionless granular bed by fluid flow over it.

The equation for cohesionless active earth pressure is expressed as:

Type 2 consists of boulders supported by a cohesionless sandy matrix that continues from the surface down through the profile.

The flow of cohesionless grains in fluids.

Liquified/fluidized flow - Formed in cohesionless granular substances.

The steepest angle that a cohesionless slope can maintain without losing its stability is known as its angle of repose.

For example, loess soils, fine cohesionless silts, highly turbid liquids, and microorganism laden liquids (farm runoff) are troublesome and generally require specialized testing evaluations.

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 the resultant force is angled parallel to the backfill surface.

In cohesionless soils, these waves create liquefaction that is followed by the compaction of the soil, and in cohesive soils, they create an increased amount of pore water pressure that is followed by the compaction of the soil.

The resistance of the cohesionless soil to liquefaction will depend on the density of the soil, confining stresses, soil structure (fabric, age and cementation), the magnitude and duration of the cyclic loading, and the extent to which shear stress reversal occurs.

Since this early work, the results of large-scale triaxial test on isolated geocells has demonstrated that cellular confinement imparts apparent cohesion to cohesionless compacted granular material on the order of 169 kPa - 190 kPa (3500 psf - 4000 psf).
