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

E3S 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-

Variation in principal curvature of air-water interface inside and outside shear band of dense unsaturated sand [PDF]

E3S Web of Conferences
Triaxial compression tests were conducted on dense unsaturated sand specimens under constant suction and constant water content conditions. X-ray micro-computed tomography (CT) scans were performed at different deformation stages to visualize the ...

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

Iraqi 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 ...

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,
