Miniature triaxial tests to investigate effects of pore fluid salt concentration on the mechanics of clays

Mitigating the land degradation caused by salinity is a national priority. In the urban environment salinity and the associated waterlogging have the potential to seriously degrade infrastructure and domestic housing. Currently the effects of salinity on the mechanical response of the ground are not well understood and there is a paucity of engineering models capable of predicting ground behaviour. This project aims to address this situation by providing new knowledge and understanding of how changes in salt concentration affect the soil, and by developing models capable of predicting the observed behaviour. This will assist in the development of rational approaches to mitigate the effects of salinity.
