Methods of Soil Water Collection at Different Matric Suctions

open access: yesJapanese Journal of Limnology (Rikusuigaku Zasshi), 1978
To investigate the transport mechanism of solutes in soil water in the unsaturated zone, collection of soil water samples having different matric potential is necessary. Three methods originally developed for the purpose of measuring matric suction, i. e., the centrifuging, the pressure membrane, and the vapor pressure depression methods, were used to ...

Characterizing the variation of small strain shear modulus for silt and sand during hydraulic hysteresis

open access: yesE3S Web of Conferences, 2016
Experimental studies have indicated that the small strain shear modulus, Gmax, of unsaturated silt and clay has a greater amount during imbibition than during drainage, when presented as a function of matric suction.

Effect of Matric Suction on Shear Characteristics of Unsaturated Fraser River Sand

open access: yes, 1998
This paper discusses the shear strength and volume change characteristics of a loose Fraser River sand. Suction-controlled simple shear tests were carried out for the unsaturated sand.

Instrumented model slope to investigate the influence of rainfall and slope gradient on matric suction

open access: yesJurnal Ilmiah SINERGI
Prior researchers indicated that prolonged and heavy rainfalls primarily trigger major landslides in Malaysia. This study was carried out to investigate the influence of rainfall on the matric suction of silty sand slopes through a small-scale model.

The effects of grass and rainfall pattern on the matric suction of acidic soil slopes [PDF]

open access: yes, 2019
Among the mechanism that leads to slope failures are that the matric suction starts to decrease when water infiltrates the soil. Although many studies have been carried out to improve stability of slope, most studies often ignore the influence of matric ...

EXPERIMENTAL STUDY OF MODEL PILED RAFT FOUNDATION EMBEDDED WITHIN PARTIALLY SATURATED COHESIONLESS SOILS

open access: yesJournal of Engineering and Sustainable Development, 2018
This paper presents an experimental study conducted on model piled rafts in partially saturated sandy soil. The aim of the experimental program is to study the effect of matric suction on the load carrying capacity of piled rafts embedded within ...

THE IMPROVEMENT OF GYPSUM SAND SOILS IN UNSATURATED CONDITIONS USING A MODIFIED OEDOMETER DEVICE

open access: yesMağallaẗ Al-kūfaẗ Al-handasiyyaẗ
This work offers recommendations on the best percentages of CKD (Cement Kiln Dust) to use for soil stabilization to reduce compressibility problems 1%, 2%, 3%, 4%, and 5% for projects where gypsum sand soil is common.

Reconciling soil-water retention properties and shear strength parameters of compacted clayey soils via suction-controlled ring shear testing

open access: yesE3S Web of Conferences, 2016
A preliminary experimental program has been undertaken to assess suction-controlled peak and residual shear strength properties of a statically compacted, moderate plasticity clayey soil. The experimental program was accomplished in a fully servo/suction-

Finite Element Simulation of the Bearing Capacity of an Unsaturated Coarse-Grained Soil

open access: yesIraqi Journal of Civil Engineering, 2012
This study proposed a procedure to define the soil-water characteristic curve and convert it into a relation between void ratio and matric suction. The resulting H-modulus function was used in finite element analysis of a footing on unsaturated coarse ...
