Governing failure mode of unsaturated soil slopes under rainwater infiltration

E3S Web of Conferences, 2016
Due to rainwater infiltration and loss of matric suction above the wetting font, both translational and rotational slips may occur in an unsaturated soil slope. It is useful to know which failure mode is more critical.

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

E3S 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.

Methods of Soil Water Collection at Different Matric Suctions

Japanese 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 ...

Density Influence on Matric Suction of the Eolian Sand under the Condition of Loop of Dehumidifying and Humidifying Process

, 2011
The matric suction has very important influence on the characteristics of unsaturated sand; and it is closely relevant to density. In order to discuss the relationship among the matric suction, water content and dry density, the matric suction of the ...

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

Jurnal 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.

An equation for predicting shear strength envelope with respect to matric suction

, 2004
Determining the shear strength parameters of unsaturated soils generally involves costly, time-consuming and sophisticated testing programme. This paper proposes a new method for prediction of shear strength with respect to matric suction.
