Background Moisture-induced suction changes in expansive soils due to infiltration and
evaporation result in failure of civil infrastructure. The objective of this paper was to develop …

Water content and matric suction in unsaturated soils change due to infiltration and
evaporation. For soils such as expansive clays, this results in soil volume changes and …

The prediction of seasonal soil suction changes is critical to the analysis of volume change
in unsaturated, expansive soils. A one-dimensional moisture flow model was developed to …

Expansive soils exhibit large volume changes when their water content changes. Alternate
heave and settlement due to seasonal climatic variations result in distress and damage in …

A three-dimensional moisture diffusion and volume change model Suction heave (SUCH) is
described. The model SUCH is capable of predicting soil moisture changes in terms of soil …

It is well established that damage to structures built on expansive soils is mainly caused by
changes in soil suction. Suction changes are generally attributed to changes in …

Expansive soil problem is one of the major problems in the field of geotechnical
engineering. The change in water content in unsaturated expansive soil is the major reason …

Expansive soils undergo volumetric changes due to moisture variations as a result of soil-
atmosphere interaction. In this study, the moisture-induced volumetric changes in …

Buildings constructed on expansive soils often suffer damage due to shrinkage and heave of
the soil as a result of seasonal climate change. There is a need for a better understanding of …

Climate change and severe climatic events such as long drought/rehydration periods are at
the origin of the shrinkage and swelling phenomenon in expansive soils. This phenomenon …
