Underground structures have gained importance in recent times all over the globe. Successful completion of such ventures hinges on accurate and realistic design which is neither optimistic nor conservative, and a balanced design is the need of the hour. The present work shows a comparative study on support design, such as Terzhagi's load theory and quantitative methods of Rock mass quality (Q), Rock Mass Rating of Bieniawski, and PLAXIS-2D Numerical modeling. The results obtained show that
