Assessment of the impact of climate change on an instrumented embankment: an unsaturated soil mechanics approach [PDF]

, 2011
Climate change has the potential to affect any transportation network that comprises embankments and cuttings built with soil material in an unsaturated state that is exposed to the climate.

Matric suction measurement of unsaturated soils with null-type axis-translation technique

, 2012
Matric suctions of several compacted soil specimens of a low-plastic soil were measured using null-type axis-translation technique. The study showed that in general, the dynamically compacted specimens reached equilibrium sooner than the statically ...

MEASUREMENTS OF SUCTION AND WATER CONTENT DURING SATURATION OF COMPACTED EXPANSIVE SOIL

Diyala Journal of Engineering Sciences, 2015
The change of climate gives fluctuation of water content in its result rain, evaporation, rising water ground level and evapotranspiration. The expansive soil will volume change and suction. This behavior can damage on construction structures especially,

Suction-monitored direct shear apparatus: A simple device for unsaturated soil testing

, 2013
Two very common devices used in unsaturated shear strength tests are suction-controlled direct shear apparatus and triaxial devices. During the tests, matric suction is applied to the specimen by controlling pore air and pore water pressure.

The influence of suction changes on the stiffness of railway formation

, 2011
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Proposed method for obtaining representative water content and matric suction of a cracked soil

, 2012
Water content and matric suction vary significantly throughout a cracked soil during a drying process. Therefore, it is difficult to obtain representative values of water content and matric suction of a cracked soil. In this paper, a method for obtaining
