... of consolidation tests were performed: incremental loading and long-term compression under a constant load. These tests were performed on specimens subjected to a cycle of freeze–thaw with results compared to tests on CBC in its natural state. For constant load consolidation tests, freezing and subsequent thaw...

... the fate of the contaminants after cap installation. In this study, we evaluate the fate and transport of PCBs in fine-grained, organic-rich sediments during and after the application of an in situ cap, with the goal of estimating the release of dissolved and colloid-bound contaminants from consolidating...

... The effect of tube wall friction on the microstructure of Ariake clay samples obtained from a small diameter sampler (45-mm sampler) and their strength and consolidation properties are examined from use of a color laser three-dimensional profile microscope plus unconfined compression, triaxial...

... dredged material from being a fluid to behaving like a continuum. The performed tests show that it is possible to put a sand layer on top of dredged material after a short initial consolidation phase. This indicates that dredged material at this stage is by definition a continuum. Results from special...

... A numerical model for coupled, one-dimensional, large strain consolidation and contaminant transport, called CCT1, is presented. The large strain consolidation algorithm includes all the capabilities of a previous code, CS2. The contaminant transport algorithm includes advection, dispersion...

... This paper presents a piecewise-linear model, called CS4, for one-dimensional consolidation of an accreting soil layer. CS4 was developed using a fixed Eulerian coordinate system and general constitutive relationships defined by discrete data points. The model includes the effects of vertical...

... * . The compressibility parameters κ * , λ * and μ * used within the model can be determined by standard one-dimensional consolidation tests. Applying the different methods, the calculated settlements show differences in the ratio between the primary and secondary compression as well as the distribution in time...

... This paper describes the behaviour of soft soils created by the rapid deposition of a sediment slurry and the mechanisms by which pore fluid escapes from the consolidating bed. Such rapid deposition occurs as a result of dumping dredge spoils at sea or in the case of disposing of mine tailings...

... of the high bonding, or adsorption, of the liquid phase within and around these flocs. The authors have carried out a series of tests, including consolidation and shear strength tests, in order to attempt to characterise the geotechnical engineering and consolidation behaviour of these sludges. The great...

... was designed to perform consolidation tests on large dimension specimens (Ø 250 mm, height ⩽ 60 mm). Several tests on three types of waste have been performed. Settlement and amount of exuded liquid from both upper and lower drainage interfaces has been measured under different normal stresses and initial...

... and in Rowe cell with measurement of pore pressure, adopting different load increment ratio and load permanence, were performed. The compression characteristics (C c , C α ) and the difficulties involved in reliably determining the end of primary consolidation and evaluating the permeability were investigated...

... of remediation. Design of the cap required knowledge of the consolidation behavior of the sludge. In order to analyze this behavior, a series of consolidation tests was performed. The laboratory testing program included three large-scale consolidation tests and four conventional oedometer tests. Consolidation...

... New capabilities for hydrologic property measurements in triaxial systems include: (1) volume-controlled and simultaneous measurements of hydraulic conductivity and one-dimensional consolidation (or specific storage) of a saturated test specimen; and (2) volume-controlled measurements...

... In laboratory tests such as triaxial, consolidation, and scale model tests, the laboratory specimens are often loaded at a different rate than the soil in the field. It is known that clayey soils exhibit rate dependent volume change (secondary compression) and rate dependent shear strength...
