stress, preconsolidation

stress, preconsolidation: The maximum antecedent effective stress to which a deposit has been subjected, and which it can withstand without undergoing additional permanent deformation. Stress changes in the range less than the preconsolidation stress produce elastic deformations of small magnitude. In finegrained materials, stress increases beyond the preconsolidation stress produce much larger deformations that are principally inelastic (nonrecoverable) [21].

Consolidation (soil) — Consolidation is a process by which soils decrease in volume. According to Karl Terzaghi consolidation is any process which involves decrease in water content of a saturated soil without replacement of water by air. [citation needed] In general… … Wikipedia
Oedometer test — Incremental Loading frame developed by Bishop An oedometer test is a kind of geotechnical investigation performed in geotechnical engineering that measures a soil s consolidation properties. Oedometer tests are performed by applying different… … Wikipedia
Soil mechanics — is a discipline that applies principles of engineering mechanics, e.g. kinematics, dynamics, fluid mechanics, and mechanics of material, to predict the mechanical behavior of soils. Together with Rock mechanics, it is the basis for solving many… … Wikipedia
coefficient of volume compressibility — The compression of a clay (aquitard) per unit thickness, due to a unit increase of effective stress, in the load range exceeding preconsolidation stress. It is expressed by the equation in which e0 is the initial void ratio. Units are usually… … Lexicon of Cave and Karst Terminology
