Determination of Consolidation Parameters by Selfweight Consolidation Test in Centrifuge

1986
Consolidation parameters such as volume compressibility, mv, and permeability, k, of very soft slurry clay are difficult to obtain from a conventional oedometer test. A selfweight consolidation test in a centrifuge is available as an alternative test. The mv value is calculated from the f-log p relationship which is obtained from a correlation between ...

Consolidation Testing with Back Pressure

Journal of the Soil Mechanics and Foundations Division, 1964
It is important that laboratory tests on soils saturated in situ be performed on fully saturated specimens. The use of back pressure, common in triaxial testing, has been extended to consolidation testing. A new consolidometer developed for tests with and without back pressure is fully described and back pressure testing procedures are outlined ...

Automation in Consolidation Testing

1960
Of all the various tests performed on soils, the most time consuming one is the laboratory test for consolidation. Essentially this test consists of determining the time-compression relation under constant loading of a laterally confined soil mass. Ideally, a continuous record of the relation would be desirable.

Consolidation Testing—A Comparative Study

1986
The knowledge of the preconsolidation pressure, p′e, of an overconsolidated clay is of vital importance in the settlement analysis of structures. It has been found that the semigraphical methods to determine p′e proposed by Casagrande, Burmister, and Schmertmann are not completely satisfactory for sensitive clays.

Rapid method of consolidation testing

Canadian Geotechnical Journal, 1999
The determination of consolidation characteristics forms an important aspect in the design of foundations and other earth-retaining structures. The conventional consolidation test as originally proposed by Terzaghi takes considerable time (more than 15 days in highly compressible soils with low coefficient of consolidation) and effort.

Controlled Gradient Consolidation Test

Journal of the Soil Mechanics and Foundations Division, 1969
A new consolidation test based upon maintaining a constant pattern of hydrostatic excess pressure in the test specimen is described. New apparatus and testing technique are developed for the test. The controlled gradient test can be performed at a slow rate strain that is practically constant for a particular test.

Report of Consolidation Tests with Peat

1952
In 1945 two earth-filled concrete barricades 1200 ft long, 10 ft wide and 20 ft high were built on a site reclaimed from a tidal marsh. No soil investigation was made prior to construction but since the soil conditions were known to be poor, sand drains 50 ft deep, 18 in.

The Application of Controlled Test Methods in Consolidation Testing

1952
The consolidation test is a fundamental stress-strain and strength test for soils. It has important applications in soil and foundation work, not only for estimating the probable magnitude and time-rate of settlement of foundations to be expected under loadings imposed by structures and determining the adequacy of the supporting soils, but also as the ...
