Organic Material and Soil Compressibility
Journal of the Geotechnical Engineering Division, 1980Compression tests on model organic soils have shown that higher organic fractions significantly increase soil compressibility. Precise control over organic content, fiber type and size, and mineral type in the model soil were made possible using kaolinite-fiber mixtures.

Compressibility characteristics of soils
Geotechnical and Geological Engineering, 2005Compressibility characteristics of soils forms one of the important soil parameters required in design considerations. Compression index, C c , which is the slope of the linear portion of void ratio, e vs. logaritham of effective pressure p(log p) relationship, is extensively used for settlement determination.

Reconsidering Secondary Compressibility of Soil
International Journal of Civil Engineering, 2016The effects of effective stress and void ratio on the secondary compressibility of the sandy and clayey soils were investigated in this study. The coefficient of secondary compression of Ottawa sand in single stage and stepwise loading tests increases with effective vertical stress while that of saturated kaolinite decreases with effective vertical ...

SPT and the compressibility of cohesionless soils
2021Besides the methods of direct settlement estimates from SPT results there are other ones which introduce the use of modulus of compressibility, estimated from SPT tests along with the applications of the theory of elasticity, as also the method suggested by Parry which has the form of an elastic equation where E is replaced by N.

Soil compressibility as measured in the oedometer
Géotechnique, 1978The evaluation of oedometer tests and the calculation of settlement can be based on the linear plot of the constrined modulaus D with consolidation pressure p. This plot has a U shape and presents the following advantages: it reveals the minumum value of D and the pressure where it occurs; it shows the range of pressures where the soil is strain ...

In this chapter, the probabilistic porous-solid model is used to determine the mean effective stress of soils at failure. The plots of the deviator stress against the mean effective stress show a unique failure line for a series of triaxial tests performed at different confining net stress and suctions for both wetting and drying paths.
