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.
