Executive Summary :

Arunachal Pradesh, located in the north-eastern Himalayan region of India, is highly vulnerable to earthquakes and related hazards due to its high seismic zone V. Factors such as weak geological strata, hydrological conditions, and anthropogenic activities contribute to slope failures. To address this issue, an integrated approach using various simulation techniques is proposed. These techniques can help design a comprehensive system for evaluating slope instabilities and identify potential failure mechanisms. Numerical simulation approaches, such as finite element and distinct element methods, have gained global importance in civil, mining, and geological engineering. However, most previous studies have not considered the representation of exact failure zones and the modification of forces acting on the slope over time. The distinct element method is particularly beneficial for identifying exact failure zones and estimating displacement values. The study area, covering 98 kilometers along National Highway 13 in Arunachal Pradesh, is cut through several rock and debris slopes. The aim is to establish a coherent system that can set a benchmark for stability assessment of road-cut slopes.
