Цел на проекта

Rainfall-triggered landslides pose increasing risks in Europe and Asia, with granite residual soil (GRS) slopes particularly vulnerable due to their high sensitivity to water. However, the hydro-mechanical degradation mechanisms of GRS remain poorly understood, and there is a lack of low-carbon, eco-sustainable solutions to ensure both short- and long-term slope stability. This project aims to develop an eco-sustainable, synergistic reinforcement strategy for GRS slopes by integrating protein-based hydrogels with vegetation. The approach combines experimental investigations and advanced modelling to achieve this objective. On the experimental front, the project will evaluate how hydrogels enhance GRS stability while gradually degrading to facilitate seed germination, enabling a smooth transition from initial reinforcement to long-term, vegetation-based stabilisation. Planned activities include CT-coupled triaxial tests to capture microstructural evolution and strength changes, hydrogel–seed–soil compatibility trials, and large-scale slope model experiments. On the theoretical front, a novel root-growth phase-field model will be developed to simulate root development and hydro-mechanical coupling, rigorously calibrated against experimental results. Aligned with the MSCA Work Programme, this project will deliver scientific impact by advancing multiscale modelling of eco-friendly soil reinforcement, economic and technological impact by creating a cost-effective, patentable alternative to conventional slope stabilisation, and societal impact by mitigating landslide risks and supporting climate adaptation in vulnerable regions.
