Matric Suction in Recycled Unbound Granular Materials
Geo-Congress 2014 Technical Papers, 2014 The matric suction within unbound granular materials (UGMs) can be small when compared with cohesive soil, however suction can influence the engineering behavior of UGMs. Unfortunately, there are few studies on the potential matric suction in UGMs. This paper presents matric suctions for seven recycled products and one virgin aggregate.

Preliminary Analysis on Matric Suction for Barren Soil
IOP Conference Series: Materials Science and Engineering, 2016 Abstract Most research conducted on slope failures can broadly be attributed to the convergence of three factors, i.e. rainfall, steepness of slope, and soil geological profile. The mechanism of the failures is mainly due to the loss of matric suction of soils by rainwater.

An evaluation of the effect of matric suction on the dynamic strain-dependent parameters of an unsaturated silt [PDF]
E3S Web of Conferences, 2023 This research investigates the influence of matric suction on the variation of shear modulus and damping ratio of a silty soil in very small to medium shear strain levels.

On equations for the total suction and its matric and osmotic components
Cement and Concrete Research, 2008 A clear fundamental understanding of suctions is crucial for the study of the behaviour of plastic cement mortar and concrete, including plastic shrinkage cracking. In this paper, the expression relating the change in free energy of the pore water with an isothermal change in pressure is first derived.

Effect of contact angle hysteresis on measuring matric suction in unsaturated sandy soil
Geomatics, Natural Hazards & Risk, 2023 The contact angle plays an important role in matric suction of unsaturated soils, but few studies consider the effect of contact angle hysteresis on matric suction. In this paper, taking sandy soil as an example, the influence of contact angle hysteresis

Hydro-mechanical modeling of a vegetated slope subjected to rainfall [PDF]
E3S Web of Conferences, 2023 Shallow landslides triggered by heavy rainfalls have caused casualties and economic losses to domestic infrastructures and industries worldwide. Rainfall mainly reduces the soil matric suction and the shear resistance, resulting in shallow landslides ...

Effects of water/salt phase transition on matric suction of sulfate saline soil
Yantu gongcheng xuebao, 2022 The sulfate saline soil is the main type of saline soil in cold and arid regions of Northwest China. As the environmental temperature changes, the ice formation and salt crystallization may change the matric suction of saline soil.

TOTAL AND MATRIC SUCTION MEASUREMENT OF UNSATURATED SOILS IN BAGHDAD REGION BY FILTER PAPER METHOD
Journal of Engineering, 2023 Soil suction is one of the most important parameters describing the moisture condition of unsaturated soils. The measurement of soil suction is crucial for applying the theories of the engineering behavior of unsaturated soils.

Relationship between the matric suction and the shear strength in unsaturated soil
Case Studies in Construction Materials, 2020 To understand the shear strength properties for unsaturated soil with different matric suction values, a modified triaxial test device was used. The matric suction is considered an important contributor to unsaturated shear strength properties.

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 ...
