Los suelos arcillosos tienen la propiedad de hincharse en presencia de agua y contraerse en su ausencia, produciendo así grietas por desecación que alteran significativamente su desempeño mecánico e hidráulico. En este estudio se investigó la m

The behaviour of soils undergoing deformation due to changes in water content can be described using Soil Shrinkage Curves (SSCs). The SSCs are normally influenced by several factors as the soil’s fabric, different compaction levels, residual void

In the transport of heat in porous media, diffusion generally dominates over advection due to slow fluid velocities imposed by low permeability. This is the reason why standard Galerkin formulation leading to extra non-symmetric matrix terms may be s

Cracking in desiccating soils is an important topic in soil compacted works. This paper presents an experimental study on the effect of compaction on the cracking of a silty clay soil, which was subjected to drying conditions. The specimens were comp

Soil surfaces in contact with the atmosphere are interfaces where different processes play an important role in triggering the formation of cracks due to desiccation. Empirical evidence shows that variables such as solar radiation, wind speed or rela

This paper presents a numerical study of the desiccation processes of low-plasticity clayey soils that usually result in shrinkage and often in cracking. For the theoretical development of the numerical model, concepts of Unsaturated Soils Mechanics

This paper presents the results and analysis of cracking tests carried on samples of silty clay which were subjected to a drying-wetting-drying cycle to study the effect of cyclic change of moisture on the cracking behaviour. During tests, temperatur
