Retaining walls play a crucial role in civil engineering projects, providing stability to soil, preventing erosion, and mitigating landslides. To design and analyse these walls effectively, a profound understanding of soil mechanics, structural engineering principles, and various wall configurations is required. One notable configuration is the Cantilever Retaining Wall, which is known for its simplicity and effectiveness in resisting lateral earth pressures. However, for taller retaining walls, incorporating a column has shown potential in achieving greater cost-efficiency. This research aims to conduct a comprehensive analysis of cantilever retaining walls, comparing those with and without a column system. The study utilizes manual calculations, as well as software tools like STAAD Pro and Excel spreadsheets, for design optimization. Adherence to the guidelines specified in the Indian Standard IS 456:2000 for reinforced concrete structures ensures compliance with industry standards. The research involves a thorough examination and design of both the Cantilever Retaining Wall (CRw) and the Column Cantilever Retaining Wall (CCRw), considering a 35-meter span and heights ranging from 3 to 9 meters. Through a comprehensive evaluation of construction costs, this study concludes that the CCRw configuration offers superior costeffectiveness compared to the CRw configuration.
