Abstract:
The intensifying coupling between climate change and engineering disturbances exacerbates geological hazards. Prevailing mitigation strategies relying on rigid "single-phase over-reinforcement" designs, However, fail to adapt to recurrent extreme climate events and persistent dynamic disturbances from chronic engineering activities, whilestruggling to balance multi-objective requirements for safety, cost-effectiveness, and sustainability. This study proposes a multi-phase dynamic reinforcement optimization method for landslide mitigation based on system resilience theory, applicable throughout the whole-life cycle of landslides. Systematic analysis of shear strength parameter evolution in slip zone soils and resistance degradation mechanisms in anti-slide systems under periodic disturbances (e.g., rainfall infiltration and freeze-thaw cycles), enabled the establishment of time-dependent functional performance equations for landslide systems. Examination of resilience evolution in exponential-type landslides, step-type landslides, and red-bed landslides with anti-slide pile systems led to the development of optimal reinforcement strategies. Results demonstrate that the system functional resilience evaluation metric effectively quantifies landslide system performance under varying disturbance conditions. Furthermore, analysis of economic losses and scale characteristics of 33 landslides in Xinjiangestablished preliminary empirical relationships. Based on this analysis, the study investigated the impacts of different reinforcement strategies on total economic costs under identical disturbance cycles. The findings reveal that total landslide disaster costs initially decrease and subsequently increase with reduced critical system functionality, demonstrating the existence of optimal reinforcement strategies. Application of resilience theory to whole-life cycle management of landslide mitigation addresses knowledge gaps in stability evaluation under periodic disturbances, providing theoretical and technical breakthroughs for resilient governance of critical engineering projects in climate-sensitive regions.
