The present paper deals with different empirical methods and finite element method of slope stability analysis along National Highway (NH)-7, in Uttarakhand, India. The highway is only path in the hilly terrain of Lesser Himalayan for the public transport and have strategic importance due to militaries possession routes. This route is also significant due to having many holistic places, connecting to this. There was numerous landslides happened along the Highway in past due to various natural and anthropogenic activities. Hence, keeping an eye to the socio-economic development of the distant area, slope stability analysis is very crucial along the road cut sections. To identify the vulnerable locations and to collect the geotechnical data, the field investigation was carried out between Shivpuri to Byasi along NH-7 in Garhwal, Uttarakhand. Then geotechnical data was intended followed by rock mass characteristic, kinematic analysis and Q_slope stability. Additionally, to review the stability results, numerical simulation (finite element method) was employed and slope mass behavior and failure mechanism of cut slopes were also evaluated. The rock mass characteristic and kinematic analysis illustrate normal and good variety of rock mass mainly wedge mode with flexural toppling of failure. The slope mass rating, continuous slope mass rating and also Q_slope stability analysis showed, road cut slopes are critically stable and unstable. The results of different empirical methods shows a decent correlation between them. Further the numerical simulation analysis also evaluates that two cut slopes are unstable and other one is critically stable. This substantial empirical and numerical analysis of cut slopes provides a collective approach to stable and develop the holistic road corridor in Himalayan terrain.

本文研究了印度北阿坎德邦沿国家公路（NH）-7的边坡稳定性分析的不同经验方法和有限元方法。高速公路仅是小喜马拉雅山丘陵地区的公共交通路径，由于拥有军人，因此具有战略重要性。由于具有许多整体位置，因此这条路线也很重要。由于各种自然和人为活动，过去沿高速公路发生了许多滑坡。因此，要注意偏远地区的社会经济发展，边坡稳定性分析在道路切面沿线至关重要。为了确定脆弱的地点并收集岩土数据，在北阿坎德邦加尔瓦尔的NH-7沿Shivpuri至Byasi之间进行了实地调查。_边坡稳定性。此外，为了评估稳定性结果，采用了数值模拟（有限元方法），并评估了边坡的质量特性和挖方边坡的破坏机理。岩体特征和运动学分析说明岩体的正常变化和良好变化，主要表现为楔形模态和弯曲破坏。斜率质量额定值，连续斜率质量额定值以及Q_斜率稳定性分析表明，路cut边坡极为稳定和不稳定。不同经验方法的结果表明它们之间有很好的相关性。进一步的数值模拟分析还评估了两个切坡是不稳定的，而另一个是临界稳定的。对挖方坡度的大量实证和数值分析为在喜马拉雅地形中稳定和发展整体道路走廊提供了一种统一的方法。
