Predicting Bimodal Soil–Water Characteristic Curves
Journal of Geotechnical and Geoenvironmental Engineering, 2005Failure 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 ...

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 ...

A method for estimating soil water characteristic curve with limited experimental data
, 2020Because of the difficulty to reach high suction at the residual state of unsaturated soils, the saturation-suction experimental data for soil water characteristic curve (SWCC) is often limited and incomplete, which will lead to unreliable estimation of ...

Probabilistic Analysis of Soil-Water Characteristic Curves
Journal of Geotechnical and Geoenvironmental Engineering, 2010Direct 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.

Influences affecting the soil-water characteristic curve
Journal of Zhejiang University-SCIENCE A, 2005The soil-water characteristic curve (SWCC) is the primary partially saturated soil information as its behavior and properties can be derived from it. Although there have been many studies of unsaturated soils and the SWCC, there is still no combined constitutive model that can simulate soil characteristics accurately. In cases when hydraulic hysteresis

A novel approach for modelling soil–water characteristic curves with hysteresis
Computers and Geotechnics, 2010Soil-water characteristic curves can be defined as the relationship between the degree of saturation and suction of an unsaturated soil. Geomaterials, such as clays, sands, and geotextiles, usually exhibit hysteresis between drying and wetting curves. In addition, each drying and wetting curve is nonlinear in shape, which may be approximated by sigmoid

Soil-water characteristic curve and consolidation behavior for a compacted silt
Canadian Geotechnical Journal, 2007Measurement of the soil-water characteristic curve (SWCC) in the laboratory is commonly conducted under zero confining pressure. However, in the field, the soil is under a confining stress. Therefore, it is important to study the effects of the confining stress on SWCC.

Mathematical attributes of some soil—water characteristic curve models
Geotechnical & Geological Engineering, 2001Numerous mathematical models have been proposed in the research literature to represent soil—water characteristic curve data. A number of proposed mathematical models are summarized and the significance of each of the associated soil parameters is illustrated. The advantages and disadvantages of the various mathematical models are outlined.

Nonlinear Curve-Fitting Procedures for Developing Soil-Water Characteristic Curves
Geotechnical Testing Journal, 2006Abstract Measurement of soil suction for developing soil-water characteristic curve, SWCC, is a laborious and time-consuming task. On the other hand, commercially available databases that employ empirical fitting functions or the estimation algorithms for establishing the SWCC are quite costly and hence, beyond the reach of many. In such
