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.

缓解盐碱化造成的土地退化是国家优先事项。在城市环境中，盐碱化和随之而来的内涝有可能严重破坏基础设施和住宅。目前，盐度对地面力学响应的影响还不是很清楚，能够预测地面行为的工程模型也很少。这个项目旨在通过提供关于盐分浓度变化如何影响土壤的新知识和理解，并开发能够预测观察到的行为的模型来解决这种情况。这将有助于制定合理的办法来减轻盐度的影响。
