Question: What Is The Difference Between Consolidation And Settlement?

What is CV in consolidation?

cv is the coefficient of consolidation and is a measure of the rate at which the consolidation process proceeds.

In many consolidation problems in which the total stress σ remains constant throughout..

How is consolidation settlement calculated?

The primary consolidation settlement can be calculated from the coefficient of volume compressibility mv, which can further lead to the Young’s modulus E′ = (1 + v′)(1 − 2v′)/[mv(1 − v′)], with an assumed Poisson’s ratio v′.

What is consolidation test?

Consolidation test is used to determine the rate and magnitude of soil consolidation when the soil is restrained laterally and loaded axially. The Consolidation test is also referred to as Standard Oedometer test or One-dimensional compression test.

How can I reduce my consolidation settlement?

Note: the consolidation settlement can be reduced by conducting any of the following: 1. Increase the length of piles (when the length of piles are increased, “H” value in the preceding equation would reduce. “H” is the thickness of the compressible portion of the clay layer).

What is compaction factor for soil?

If you combine the two factors you get a factor (Spike’s compaction factor) which will convert loose state volume to compacted volume of the material. You can use this factor to estimate the amount of material you need to bring in for a certain area that needs to be compacted.

What is normal consolidation?

• Normally Consolidated Soil: A soil that has never experienced a vertical effective. stress that was greater than its present vertical effective stress is called a normally. consolidated (NC) soil.

What do you mean by consolidation?

to bring together (separate parts) into a single or unified whole; unite; combine: They consolidated their three companies. to discard the unused or unwanted items of and organize the remaining: She consolidated her home library.

What is consolidation and settlement?

When a saturated soil is loaded externally, GL saturated claythe water is squeezed out of the soil and the soil shrinks, over a long time may be upto several years depending upon the permeability of the soil this whole phenomenais called consolidation. …

What is the purpose of consolidation?

1. The purpose of consolidated financial statements is to present, primarily for the benefit of the owners and creditors of the parent, the results of operations and the financial position of a parent and all its subsidiaries as if the consolidated group were a single economic entity.

What is the process of soil consolidation?

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.

What are the types of consolidation?

There are three consolidation methods, which are used depending on the strength of the Parent company’s control or influence (see also Significant influence): Full consolidation, Proportionate consolidation, and the Equity method.

What is difference between compaction and consolidation?

Compaction is the compression of soil by the expulsion of air from the voids of the soil. Consolidation is the compression of soil by the expulsion of water from voids of the soil. It is a quick process. It is a slow process.

Why is soil consolidation important?

Compressibility of clays is mainly caused by expulsion of water between the soil grains and slipping of particles to new position to attain greater densities. Consolidation plays an important role in stability analysis for the embankment, footings or a column constructed on clayey soils.

What will be the time required for 90% consolidation?

A clay layer 3 m deep is sandwiched between two pervious layers. The soil reaches 90% consolidation in 3 years.

What is black cotton soil?

Black cotton soils are clay rich soils formed in regions (tropics and subtropics) having poor drainage conditions. Such conditions favour the formation of such clays which have montmorillonite clay mineral as the principal clay mineral.
