This project aims to advance fundamental knowledge on the complex behaviour of reactive soils in the context of resilient geotechnical infrastructure. This research falls within the research priority “Environmental Change”, as geotechnical infrastructure need to sustain the impact of ever more frequent and more intense climatic actions. Attention will focus on the effect of suction on volume change and shear strength of reactive soils, two poorly understood features, and will produce a swelling model and a soil-deformable structure interaction model. After validation by a case study, the models will have the potential to empower industry to produce geotechnical infrastructure that can better sustain climatic actions.

这个项目的目的是在具有弹性的岩土基础设施的背景下，促进关于活性土壤复杂行为的基本知识。这项研究属于研究重点“环境变化”，因为岩土基础设施需要承受更频繁和更强烈的气候行动的影响。人们将关注吸力对活性土体积变化和抗剪强度的影响，这是两个鲜为人知的特征，并将产生膨胀模型和土-变形结构相互作用模型。经过案例研究的验证，这些模型将有可能使工业生产出能够更好地支持气候行动的岩土基础设施。
