Geosynthetic-reinforced soil (GRS) bridge abutments are increasingly used in transportation engineering. However, limited research has been conducted on the failure mechanisms of GRS bridge abutments, particularly the connection failures between reinforcement and facing. In this study, large-scale model tests were carried out to investigate the impact of connection failure between reinforcement and facing on the overall stability of GRS bridge abutments. The tests focused on a weaker connection configuration using low-strength cable ties subjected to high vertical loads. Photographic analysis was employed to document deformation and failure processes, while additional data were collected via sensors to monitor settlement, lateral displacement, and strain behavior during loading. The results indicated that inadequate connections between reinforcement and facing could result in progressive deformation, panel detachment, backfill leakage, and collapse under high loads. These findings underscore the importance of a strong connection between reinforcement and facing for maintaining structural stability. To address these issues, improved measures were proposed and validated, demonstrating significant enhancements in load-bearing performance and resilience.
