Abstract—The contamination of significant quantities of soils and sediments with uranium and other actinide elements as a result of nuclear activity poses many environmental risks. The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a ...

Unsaturated soils exhibit water retention hysteresis, with different behaviour during drying and wetting paths. Water hysteresis has often been modelled using expressions for the main curves that are unsatisfactory at low values of degree saturation. In addition, effect on unsaturated hydraulic conductivity typically not explicitly considered. This paper presents a new hysteretic constitutive m...

Bearing capacity of single piles are occasionally predicted using the renowned theoretical methods (α and β methods). These based on laboratory tests, which can be time-consuming, but also applicable in foundation engineering practice for unsaturated soils. Full-scale pile load tests were carried out bored equipped with Expander Body Systems Federal District Brazil, known its unsaturated, colla...

Soils with two subcurves of Soil-Water Characteristic Curve (SWCC) (dual porosity soils) might be found within various residual soils. located in different depths have confining pressure. Residual soils are the unsaturated zones due to deep groundwater table. There is a linear correlation between hydraulic properties soil area and that its properties. This study aims examine influence pressure ...
