preconsolidation pressure

[¦prē·kən‚säl·ə′dā·shən ‚presh·ər]
(geology)
The greatest effective stress exerted on a soil; result of this pressure from overlying materials is compaction. Also known as prestress.

The preconsolidation pressure was significantly related with soil bulk density, soil water content, and clay content (R 2 = 0.
The clay was mixed with water into slurry (moisture content = 72 %) and consolidated under the preconsolidation pressure of 98 kPa in a consolidometer.

As shown in Figure 1, the preconsolidation pressure corresponds to a point taken on the e versus [Sigma]' curve where there is a transitional break in slope.
pc] is the preconsolidation pressure, and [[Sigma]'.
A natural assumption, due to the presence of glacial overburden during deposition, is that basal tills are highly overconsolidated, and their preconsolidation pressure can be approximated by multiplying the specific weight of ice by the thickness of the ice sheet.
The point that separates these two regions is called the preconsolidation pressure or precompression stress ([[sigma].
Thus, the aim of the present study was to establish the relationship between the preconsolidation pressure, soil water retention characteristics, and texture of representative Latosols from the Brazilian Cerrado region.
