Variability Characterization of SWCC for Clay and Silt and Its Application to Infinite Slope Reliability

Journal of Materials in Civil Engineering, 2021
A novel statistical framework was developed to quantify the variability of the fitting parameters of the soil-water characteristic curve (SWCC). Reliable estimation of the mean, standard deviation, and associated probability density function (PDF) of the

Influence of Initial Water Content and Specimen Thickness on the SWCC of Fine-Grained Soils

International Journal of Geomechanics, 2013
Earlier researchers have demonstrated that the compaction effort and water content, type of soil and mineralogy, void ratio, fabric, and stress history influence the soil-water characteristics curve (SWCC) of fine-grained soils to a great extent. However,

An Oedometer-Type Pressure Plate SWCC Apparatus

Geotechnical Testing Journal, 2008
Abstract A new oedometer device for SWCC determination has been evaluated by testing a wide range of soil types, and recommendations for best practices for use of this device have been made. The new device allows application and control of the net normal stress, σ−ua, in addition to the matric suction, ua−uw.

Estimation of SWCC and Permeability for Granular Soils

2020
This chapter presents a new estimation model for soil–water characteristic curve (SWCC) of granular soils with the effect of initial density. The proposed model, namely the modified Fredlund and Xing (MFX) model, is based on the Fredlund and Xing equation without increasing the number of parameters.

A New Equation for SWCCs of Unsaturated Soils

2018
In the current geotechnical engineering practice, soil-water characteristic curves (SWCCs) are essential for quantifying the mechanical responses of unsaturated soil. The SWCC can be measured from laboratory or estimated from some empirical equations.

Modified Grading Curve – SWCC Relations

2012
In the ongoing research a topological interpolation method was elaborated over the N -1 dimensional space of the grading curves – represented by a N -1 dimensional simplex - using c N 2 data. The surface is selected on the basis of the grading entropy concept and the interpolated function is extended to the whole simplex by the grading entropy map.

Physical Modeling of SWCC for Granular Materials

2007
A physically model was used in this study to estimate the soil–water characteristic curve (SWCC) of granular materials in case of Hostun sand. Based on soil parameters and pore geometry the main drainage and main imbibition process as well as a scanning drainage and scanning imbibition process was determined.

Materials performance and failure evaluation in SWCC MSF plants

Desalination, 1994
Abstract An MSF plant is subjected to different forms of deteriorations due to the use of a wide variety of materials and existence of diverse types of environments. It is well established that seawater and uncondensed gases are responsible for the majority of the failures reported in desalination plants.
