δ c is the settlement due to consolidation. C c is the compression index. e 0 is the initial void ratio. H is the height of the compressible soil. σ zf is the final vertical stress. σ z0 is the initial vertical stress. When stress is removed from a consolidated soil, the soil will rebound, regaining some of the volume it had lost in the ...
Terzaghi's principle applies well to porous materials whose solid constituents are incompressible - soil, for example, is composed of grains of incompressible silica so that the volume change in soil during consolidation is due solely to the rearrangement of these constituents with respect to one another.
Vacuum consolidation (or vacuum preloading) is a soft soil improvement method that has been successfully used by geotechnical engineers and specialists of ground improvement companies in countries such as Australia, China, Korea, Thailand and France for soil improvement or land reclamation. [1]
Normally consolidated soil goes to critical state along the stress path on Roscoe surface. Critical state soil mechanics is the area of soil mechanics that encompasses the conceptual models representing the mechanical behavior of saturated remoulded soils based on the critical state concept.
Many systems in nature reach steady states, and dynamical systems theory describes such systems. Soil shear can also be described as a dynamical system. [22] [23] The physical basis of the soil shear dynamical system is a Poisson process in which particles move to the steady-state at random shear strains. [24]
An example of lateral earth pressure overturning a retaining wall. The lateral earth pressure is the pressure that soil exerts in the horizontal direction. It is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations and ...

The consolidation curve for a saturated clay showing the procedure for finding the preconsolidation pressure. Using a consolidation curve:(Casagrande 1936) [6] Choose by eye the point of maximum curvature on the consolidation curve. Draw a horizontal line from this point. Draw a line tangent to the curve at the point found in part 1.
