DIC-Based Investigation into Failure Mechanisms and Geogrid Optimization of Eccentrically Loaded Footings above Void

Key Points

• Failure mechanisms were observed under eccentric loading conditions, indicating critical structural vulnerabilities.
• Using digital image correlation (DIC), data on ground behavior was collected, enhancing understanding of footing performance.
• Eccentrically loaded footings were evaluated for geogrid optimization to improve load distribution above voids.
• Results indicate the potential need for reinforcement strategies to mitigate failure risks in similar geological conditions.
