Soil-Compressibility Prediction Models Using Machine ...

Support vector machines classification is used to determine the number of distinct models to be developed. Classification accuracy is used for detecting the existence of separability between different soil classes that in turn is indicative of the number of models needed.

Soil Compactability and Compressibility - ScienceDirect

1994-1-1  Compressibility is defined as the resistance against volume decrease when the soil is subjected to a mechanical load. Thus, it is described by the shape of the stress-strain curve. Compaction tests are used both for laboratory and field soil compression characterizations.

"Development of Soil Compressibility Prediction

The results confirm the need for separate models for three out of four soil types, these being Coarse Grained, Fine Grained, and Organic Peat. The models for each classification have varying degrees of accuracy. The correlations were tested through a series of field tests, settlement analysis, and comparison to known site settlement.

Soil compressibility and penetrability of an Oxisol

2007-1-1  Soil compressibilityStress–strain curves were determined using undisturbed samples (10 cm diameter and 3 cm height) taken at two depths: 5 cm (3.5–6.5 cm layer) and 15 cm (13.5–16.5 cm layer), and collected in the untrafficked interrow of poultry litter

The Compressibility Properties Of Soil In Maryland

2021-4-19  This is the degree to which a soil mass decreases in volume when supporting a load. Compressibility is reduced in a situation where there are more coarse-grained soils in contact with each other. It increases as the proportion of small particles increases and becomes highest in fine-grained soils which contain organic matter. Compressibility is approximately proportional to the plastic index. The greater the plastic index (PI), the greater the compressibility

Soil improvement for deep foundation - Liebherr

Soil improvement in the deep foundation industry. Liebherr deep foundation machines help improve the building ground. Soil stabilization offers the following advantages: the natural load-bearing capacity of the ground to support construction loads is enhanced. Furthermore, the compressibility (settlement) of the ground can be reduced.

"Development of Soil Compressibility Prediction

The magnitude of the overall settlement depends on several variables such as the Compression Index, Cc, and Recompression Index, Cr, which are determined by a consolidation test; however, the test is time consuming and labor intensive. Correlations have been developed to approximate these compressibility indexes. In this study, a data driven approach has been employed in order to estimate Cc ...
