This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will develop tools, models and theories to detect weaknesses in the design of infrastructure and its foundations built on problematic reactive soils, assess the impact and implement effective remedial measures to improve performance. The project is expected to increase efficiency through improved design and reduced damage, and save infrastructure owners, government and private, tens of millions of dollars each year.

该项目旨在开发基础知识，机械框架和实用的工程设计工具，以最大限度地减少反应性土壤对基础设施的影响。活性土在湿润或富盐地下水侵入时会发生显著的膨胀和弱化，在干燥时会收缩。这可能会对建筑物和基础设施造成无法修复的损害。该项目将开发工具、模型和理论，以发现基础设施设计中的弱点及其建立在有问题的活性土壤上的基础，评估影响并实施有效的补救措施以提高性能。该项目预计将通过改进设计和减少损坏来提高效率，并每年为政府和私人基础设施所有者节省数千万美元。
