Unsaturated Shear Strength of Compacted Clayey Soil via Suction-controlled Ring Shear Testing [PDF]
E3S Web of Conferences, 2020 An experimental program has been undertaken to assess both peak and residual shear strength parameters of statically compacted, moderate plasticity clayey soil under suction-controlled conditions, resulting in a defined set of suction-dependent peak and ...

A Trans-Scale Study on the Influence of Water Content and Particle Size on Matric Suction
Geofluids, 2023 Exploring the water retention properties of unsaturated soil from the perspective of a liquid bridge has been a popular issue in recent years. This study first measures the soil–water characteristic curves (SWCCs) of granular specimens to determine the ...

A study of the soil-water reliability model in the whole matric suction range
Shuiwen dizhi gongcheng dizhi, 2022 Soil–water characteristic curves (SWCCs) are considered as a basis for analyzing fluid–solid coupling of unsaturated soil. How to estimate the SWCC over the whole region with matric suction based on the limited local datasets is challenging.

Deformation, strength and water variation characteristics of unsaturated compacted loess
Case Studies in Construction Materials, 2022 The bearing capacity and safety of geotechnical structures are determined by the shear strength of soil. Soil is usually unsaturated in nature, and variation in unsaturated strength is very complicated.

A method for predicting the influence of matric suction changes on CPT tip resistance [PDF]
E3S Web of Conferences, 2019 The Cone Penetration Test (CPT) is a valuable tool for continuous soil profiling and estimating soil properties. A CPT sounding will often pass through the active zone of an unsaturated soil profile, near the ground surface where moisture conditions and ...

An Active Control System for Matric Suction Measurement
Soils and Foundations, 2009 Matric suction is an important stress state parameter in unsaturated soil mechanics. Many studies have been carried out in the past to determine the matric suction through direct and indirect methods. Direct measurement of matric suction has been proven possible with high-suction tensiometer; however high-suction tensiometers are still susceptible to ...

PLASTIC CRACKING OF CONCRETE – THE ROLES OF OSMOTIC AND MATRIC SUCTION [PDF]
, 2005 Plastic cracking of concrete is primarily attributable to desiccation by evaporation from unprotected surfaces. This causes high matric suctions to develop in the pore water in the voids adjacent to these surfaces. Dissolved salts in the pore water generate osmotic suctions. However, the effects of these suctions on the strength of plastic concrete are
