Bayesian estimation of soil-water characteristic curves

Canadian Geotechnical Journal, 2022
The soil-water characteristic curve (SWCC) is a significant prerequisite for studying the mechanical properties of unsaturated soil. As experimental measurement of the SWCC is time-consuming, empirical methods have been suggested to estimate the SWCC. However, the uncertainty associated with SWCC can be substantial.

Soil-water characteristic curves of clays

Canadian Geotechnical Journal, 2014
The drying suction – water content soil-water characteristic curves (SWCCs) of three clays (MX80 bentonite, yellow bentonite, and Speswhite kaolin) were experimentally determined using axis-translation, vapour equilibrium, and osmotic techniques. The shrinkage paths of the clays were established from Clod tests.

Predicting Bimodal Soil–Water Characteristic Curves

Journal of Geotechnical and Geoenvironmental Engineering, 2005
Failure of colluvial soil deposits induced by rainfall is a common geohazard in the natural terrain. Many colluvial soils are widely and gap graded with a minimal sand fraction. In order to study the pore water pressures in such gap-graded, unsaturated soil deposits through a seepage analysis and to evaluate the stability of these soil deposits, the ...

Probabilistic Analysis of Soil-Water Characteristic Curves

Journal of Geotechnical and Geoenvironmental Engineering, 2010
Direct measurement of the soil-water characteristic curve (SWCC) is costly and time consuming. A first-order estimate from statistical generalization of experimental data belonging to soils with similar textural and structural properties is useful.

Soil-Water Characteristic Curves for Compacted Clays

Journal of Geotechnical and Geoenvironmental Engineering, 1997
Soil-water characteristic curves (SWCCs) are presented for four compacted clay barrier soils that were prepared at different compaction water contents (dry, wet, and optimum water content) and compactive efforts (standard and modified Proctor). The SWCCs were measured in the laboratory using pressure plate extractors.

Soil Freezing and Soil Water Characteristic Curves

Soil Science Society of America Journal, 1966
Abstract An earlier paper suggested that the soil water characteristic (SWC) of soil should have an analogue to be called the soil freezing characteristic (SFC) that could be obtained by freezing saturated soil in an apparatus functionally related to the pressure plate apparatus.

Soil Water Characteristic Curves of Compacted Marine Clay

The Journal of Solid Waste Technology and Management, 2021
The soil water characteristics play an important role in predicting the engineering behaviour of unsaturated soils. An experimental programme was performed using pressure plate apparatus to investigate the effect of moulding water content, compactive effort and cycles of wetting and drying on Soil Water Characteristic Curves (SWCC) of compacted marine

Equations for the soil-water characteristic curve

Canadian Geotechnical Journal, 1994
The soil-water characteristic curve can be used to estimate various parameters used to describe unsaturated soil behaviour. A general equation for the soil-water characteristic curve is proposed. A nonlinear, least-squares computer program is used to determine the best-fit parameters for experimental data presented in the literature.

Soil-water characteristic curves of peaty soils

2020
In Singapore, peaty soils are found in several locations at shallow depths between 3m and 5m. Peaty soils, having low strength and high compressibility, have always been regarded as a poor geomaterial. In construction where peaty soils are encountered, they are generally replaced with more competent soil.

Soil–Water Characteristic Curve of Gypseous Soil

Geotechnical and Geological Engineering, 2014
The soil–water characteristic curve (SWCC), also known as soil–water retention curve, is a key tool in assessing the behavior and properties of unsaturated soil. The SWCC of gypseous soil with 0, 5, 15 and 25 % gypsum content was determined, using tensiometric plate, osmotic membrane and vapour equilibrium techniques, with suction pressures ranging ...
