This study introduces a new resilience assessment framework for slopes, enhancing performance evaluation during disturbances. The developed model accurately reflects slope performance variations, improving safety and informing future slope engineering research.
Area of Science:
- Geotechnical Engineering
- Civil Engineering
- Environmental Science
Background:
- Slope performance assessment is crucial for safety under disturbances.
- Existing resilience models struggle to accurately capture slope engineering characteristics.
- A need exists for specialized resilience evaluation models for slopes.
Purpose of the Study:
- To develop a novel resilience evaluation model and assessment framework specifically for slopes.
- To accurately reflect slope performance variations during disturbance and recovery.
- To provide a practical tool for engineering applications in slope stability.
Main Methods:
- Proposed a typical slope performance curve based on engineering characteristics.
- Derived a calculation formula for the slope resilience metric.
- Established a multi-indicator system and used CRITIC theory for weighting slope performance indicators.
Main Results:
- The developed framework accurately assesses slope performance variations during disturbance and recovery.
- The proposed resilience metric was 23.4% higher than existing models.
- Demonstrated applicability through a case study involving excavation and rainfall.
Conclusions:
- The study presents the first resilience assessment framework tailored for slopes.
- The framework offers a more accurate reflection of slope resilience compared to existing methods.
- This research provides a foundation for future studies in slope resilience engineering.
