Soil Freezing and Soil Water Characteristic Curves
Soil Science Society of America Journal, 1966Abstract 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 peaty soils
2020In 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, 2014The 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 ...

Water Retention Characteristics and Soil-Water Characteristic Curve Model of Weak Expansive Soil
Soil Mechanics and Foundation Engineering, 2021To investigate the water retention characteristics of weak expansive soil, the full suction range was determined for soil samples with different initial void ratios prepared according to the slurry consolidation method. Differences in water retention characteristics between samples prepared using slurry consolidation methods and those prepared using ...

Equations for the soil-water characteristic curve
Canadian Geotechnical Journal, 1994The 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 clays
Canadian Geotechnical Journal, 2014The 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.

Effects of microplastics on the water characteristic curve of soils with different textures
Chemosphere, 2022Microplastic (MP) pollution in the soil severely damages the soil structure and affects the soil water-holding property, thereby affecting the soil water characteristic curve (SWCC). After polyethylene MP (PE-MP) addition at three concentrations (0.5%, 1%, and 2%) under three particle sizes (150 μm, 550 μm, and 950 μm) and two soil textures (sandy soil

Comparison of Field and Laboratory Soil–Water Characteristic Curves
Journal of Geotechnical and Geoenvironmental Engineering, 2005Results of field monitoring of moisture content and matric suction at the crest and berm of a large cut slope in completely decomposed granite in Hong Kong are reported. Field moisture content and matric suction clearly show that the volumetric water content increases as a result of rainfall infiltration and decreases as a result of evaporation ...

Soil-Water Characteristic Curves of Stabilized Expansive Soils
Journal of Geotechnical and Geoenvironmental Engineering, 2006The engineering properties of expansive soils are conventionally improved through the use of additives such as fly ash, lime, and chemical additives. Such soils are often referred to as stabilized or modified or treated expansive soils. The soil-water characteristic curves (SWCC) of two expansive soils from Texas were measured both in natural and ...
