A Comprehensive Review of Slope Stability Analysis and Stabilization Methods

Abstract

Assessing slope stability before initiating an engineering project is fundamental for risk management, ensuring structural integrity, complying with regulations, and fostering sustainable development. It forms the bedrock of a safe and sustainable construction process, offering both short-term safety and long-term resilience. This comprehensive review paper delves into the intricate domain of slope stability analysis and stabilization methods. Focused on the pivotal field of geotechnical engineering, it navigates through the multifaceted techniques employed to assess and fortify the stability of natural and man-made slopes. The paper meticulously explores various analysis methods, including traditional limit equilibrium techniques like Bishop's and Janbu's methods, alongside advanced numerical approaches like Finite Element and Finite Difference Methods. Probability and reliability methodologies are also scrutinized, emphasizing their significance in estimating potential failure probabilities amid uncertainties. In tandem, the review elucidates an array of stabilization strategies. From geotechnical solutions encompassing slope grading, reinforcement techniques, and drainage systems to structural interventions such as retaining walls, soil nailing, and anchoring, the paper encapsulates diverse methodologies. Moreover, it encompasses chemical stabilization and emphasizes the pivotal role of monitoring, maintenance, and technological advancements in ensuring slope stability. By consolidating these methodologies and advancements, this review paper not only presents a comprehensive understanding of slope stability analysis but also sheds light on the evolving landscape of stabilization methods, striving towards enhanced safety and sustainability in engineering practices.
