Normally consolidated sand

Soil consolidation refers to the mechanical process by which soil changes volume gradually in response to a change in pressure. This happens because soil is a two-phase material, comprising soil grains and pore fluid, usually groundwater. When soil saturated with water is subjected to an increase in pressure, the … Ver mais The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. The former was based on diffusion equations in eulerian notation, … Ver mais Spring analogy The process of consolidation is often explained with an idealized system composed of a spring, a container with a hole in its cover, … Ver mais Coefficient of compressibility $${\displaystyle a_{v}={\frac {\Delta e}{\Delta \sigma _{'}}}}$$.

When Ver mais The theoretical formulation above assumes that time-dependent volume change of a soil unit only depends on changes in effective stress due to the gradual restoration of steady-state pore water pressure.
