摘要

The stability and safety of infrastructure, particularly in geologically complex and hazard-prone regions, depend heavily on a comprehensive understanding of soil behavior and environmental factors. In mountainous regions like the Jiroft Dam in Kerman Province, Iran, landslide risks present significant challenges to both civil infrastructure and the surrounding environment. Addressing these risks requires advanced methodologies for geotechnical analysis and risk management. This study focuses on assessing and mitigating landslide hazards at the Jiroft Dam, utilizing state-of-the-art numerical modeling techniques to simulate various geotechnical scenarios. Initial surveys identified a 45 cm displacement across six different survey points over a 9-month period, prompting further investigation. Through the application of advanced soil stabilization and real-time monitoring techniques, the displacement was reduced to 4 cm, demonstrating the success of targeted mitigation strategies. The Phase 2 software was used to simulate interactions between environmental factors and soil behavior under different conditions. This enabled an in-depth evaluation of soil stability and helped model multiple landslide scenarios. The study identified high-risk zones and assessed the effectiveness of various mitigation strategies, with particular concern over the potential blockage of the dam’s spillway, which could pose severe operational risks. By integrating these simulations with site-specific geological data, the study provides practical, evidence-based recommendations for reducing landslide risks and enhancing the long-term safety and resilience of the Jiroft Dam, with potential applicability to other similar regions.
