eo = Initial void ratio For very soft to soft clays (Qu between 0.25 to 0.50 tsf), the settlements computed by this method are likely to be reasonably accurate. For medium and stiff clays (Qu between 0.5 and 2.0 tsf), the actual settlements are likely to range between one-fourth and one-tenth of the computed values.

Soil mechanics - Wikipedia

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils.It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic solids and other matter.

Soil Mechanics: Stress and Strain - CED Engineering

void ratios generally indicate strong or incompressible soils; low relative densities and high void ratios may indicate weak or compressible soils. While the expressions for porosity and void ratio indicate the relative volume of voids, they do not indicate how much of the void space, Vv, is .

Coupled pore fluid diffusion and stress analysis

The void ratio is defined as the ratio of the volume of voids to the volume of solid material (see Effective stress principle for porous media). The evolution of void ratio is governed by the deformation of the different phases of the material, as discussed in detail in Constitutive behavior in a porous medium.

Void ratio - Wikipedia

where is void ratio, is porosity, V V is the volume of void-space (such as fluids), V S is the volume of solids, and V T is the total or bulk volume. This figure is relevant in composites, in mining (particular with regard to the properties of tailings), and in soil science.
