Experimental study on soil-water characteristic curve of expensive soil considering net normal stress

Yantu gongcheng xuebao, 2018
The expansive soil is a kind of special soil with swell-shrinking, fractured and over-consolidated properties. In engineering construction, the expansive soil is generally under unsaturated state and complex applied stress environment. It is practical to

SWCC model for double-pore structured unsaturated clay

Yantu gongcheng xuebao, 2022
Some mercury intrusion test results show that the soils using the compaction sample preparation method usually present a typical double-pore micro structure, while the existing unsaturated SWCC models are mostly directed to single-pore structural soils ...

Analytical reliability analysis of soil-water characteristic curve

E3S Web of Conferences, 2016
The Soil Water Characteristic Curve (SWCC), also known as the soil water-retention curve, is an important part of any constitutive relationship for unsaturated soils.

Bimodal SWCC and Bimodal PSD of Soils with Dual-Porosity Structure

Mathematical Problems in Engineering, 2022
The soil–water characteristic curve (SWCC) and pore-size distribution (PSD) are fundamental characteristics of soils that determine many physical and mechanical properties. Recent studies demonstrate that both SWCC and PSD sometimes exhibit a bimodal feature.

Bayesian Updating of Soil–Water Character Curve Parameters Based on the Monitor Data of a Large-Scale Landslide Model Experiment

Applied Sciences, 2020
It is important to determine the soil–water characteristic curve (SWCC) for analyzing landslide seepage under varying hydrodynamic conditions. However, the SWCC exhibits high uncertainty due to the variability inherent in soil.

Effect of initial void ratio on the soil water characteristics of unsaturated soil at high suctions

Shuiwen dizhi gongcheng dizhi, 2022
In arid and semi-arid regions, such as in northwestern China, unsaturated soils at high suction or over a wide suction range are widespread in various geotechnical designs.

Closed-Form SWCC Functions for Granular Mixtures

E3S Web of Conferences
Four closed-form water-retention functions (the Gardner, Fredlund – Xing, van Genuchten 4 and 5) were validated using the experimental, ideal water retention curve data of 7 granular fractions (fine gravel, sand and silt) and their 21 mixtures with fractal distribution (being similar to the Fuller curves), composed from 2 to 7 ...

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Water-holding characteristics of weathered granite soils

Yantu gongcheng xuebao, 2018
By using the pressure plate technique and the vapor equilibrium method with saturated salt solution, the water-holding characteristics of a granite double-layer soil slope with different weathering degrees are studied.
