The present work attempts to analyze the slope stability of road section along the national highway NH-1D from Sonamarg to Kargil in the erstwhile J&K, India. The rugged and treacherous terrain in this region is prone to frequent slope failures taking heavy toll of life, property and inconveniences to commuters due to disruption of vehicular movement. For slope study analysis twenty facets were chosen for detail based kinematic analysis and Rock Mass Rating (RMR) to identify the causes and types of failure and potential failure directions. The RMR values obtained from the study range from17 to 96, representing very poor to very good rating and the slopes range from completely unstable to completely stable. The kinematic analysis reveals that most joint planes intersect with each other in different directions consequently forming different potential failure modes. The study concludes that the existing slopes require urgent mitigation measures to thwart the failure.

沿 NH 1D 从 Sonamarg 到 Kargil，J&K，印度的边坡稳定性分析：对减少滑坡风险的影响

目前的工作试图分析沿国道 NH-1D 从 Sonamarg 到 Kargil 的路段的边坡稳定性。该地区崎岖险峻的地形容易发生频繁的斜坡崩塌，由于车辆通行受到干扰，给人们的生命、财产和通勤者带来了沉重的损失。对于斜坡研究分析，选择了 20 个方面进行基于细节的运动学分析和岩石质量等级 (RMR)，以确定失效的原因和类型以及潜在的失效方向。从研究中获得的 RMR 值范围从 17 到 96，代表非常差到非常好的评级，斜率范围从完全不稳定到完全稳定。运动学分析表明，大多数关节平面在不同方向相互交叉，从而形成不同的潜在失效模式。该研究的结论是，现有的斜坡需要紧急缓解措施来阻止故障。
