Abstract

In this study, analysis and stabilisation of four road-cut slopes in the lesser Himalayan region near Mussoorie, along Dehradun- Mussoorie Road, are investigated using the shotcreting and rock bolting technique. The rocks studied are calcareous in nature with varying rock mass properties. The exposure is along the road cuts with slope varying from 700 to 900, showing toppling to wedge failure. The stability analysis is performed through the Finite Element Analysis (FEA) and Factor of Safety (FOS) is evaluated using the Shear Strength Reduction Technique. The evaluation considers various conditions, including unreinforced slopes and slopes reinforced with rock bolts and shotcrete, to thoroughly assess the effectiveness of rock bolting in enhancing stability. The results indicate that rock bolting combined with shotcreting improves slope stability by approximately 10–40% across the different slopes analyzed.
