Abstract
The stability analysis of rock slopes has been a challenging task because of the presence of discontinuities in various forms which result in different types of slope failures. Discontinuities are the weakest zones in the rock mass. Failure mechanism of a rock slope mainly depends on the characteristics of discontinuities. Discontinuities in the form of joints, bedding planes, and faults create anisotropy in the rock mass. Stability assessment of rock slope is very much essential for suitable mitigation measurements. The stability of a rock slope is increased by using various stabilizing techniques. Rock bolting is one of the most common techniques used to stabilize the slope. In this paper, stability analysis of a rock slope located at Sairang station along the alignment of the Bairabi–Sairang railway project is carried out. The study mainly focuses on the kinematic analysis of the rock slope to obtain the possible mode of failure using DIPS, and the stability of the rock slope is analyzed using PHASE2 which is a finite element method-based shear strength reduction technique .
