Long-term chemically induced crumbling of unsaturated brittle geomaterials

点击翻译按钮获取中文摘要

This project will investigate the crumbling of geomaterials such as soil and rock by analysing the microscopic mechanisms controlling their deterioration in acidic water. The project will help predict weathering processes using an experimentally validated theory and innovative pore-scale numerical simulations. Expected outcomes include a detailed knowledge of the multi-scale interactions between brittle geomaterials and acidic water, leading to accurate forecasts of the long-term response of large-scale geotechnical structures. This project should provide significant benefits by improving soil management for mining remediation, increasing carbon dioxide storage efficiency, and preventing the deterioration of tailings dams.
