Slope instability is a big challenge for the population in mountainous regions. It poses a threat to life, economy, and infrastructure. For the safety of people, various prevention and precautions are taken and hence many scientific studies are going on. In the present study, the stability of the Karmi landslides zone, Bageshwar, Uttarakhand, India is assessed. Karmi village lies quite close to the northern border of India and the excavated roads are the only means of commute. The area lies in a tectonically active lesser Himalayan zone with high relief. Slope geometry was extracted using a total station, and seven different slope geometries were plotted. Soil and rock mass samples were taken and evaluated from various field and laboratory investigations. The direct shear test was performed to assess the friction angle and cohesion of the soil and rock mass. Numerical simulations viz., finite element analysis and probabilistic analysis have been applied on all seven slope sections and found that the mean and median safety factor of all the modeled slopes was 0.78 and 0.81, respectively. The study ascertains that the whole area to be quite vulnerable to failure, especially during rains, since the pore pressure build-up diminishes the shear strength of the slope forming material. Possible mitigation measures have been suggested based on the examined instability of the hill slopes.

印度北阿坎德邦巴格什瓦尔 Karmi 滑坡区评估

边坡不稳定是山区人口面临的一大挑战。它对生命、经济和基础设施构成威胁。为了人们的安全，采取了各种预防和预防措施，因此正在进行许多科学研究。在本研究中，评估了印度北阿坎德邦巴格什瓦尔 Karmi 滑坡区的稳定性。Karmi 村离印度北部边境很近，挖掘出来的道路是唯一的通勤方式。该地区位于构造活跃的小喜马拉雅地区，地势较高。使用全站仪提取坡度几何图形，并绘制了七种不同的坡度几何图形。从各种现场和实验室调查中采集和评估土壤和岩体样品。进行直剪试验以评估土体和岩体的摩擦角和内聚力。数值模拟，即有限元分析和概率分析已应用于所有七个斜坡部分，发现所有模拟斜坡的平均安全系数和中值安全系数分别为 0.78 和 0.81。研究确定整个区域非常容易发生故障，尤其是在下雨期间，因为孔隙压力的增加会降低斜坡形成材料的剪切强度。已根据山坡的不稳定性提出了可能的缓解措施。分别为 78 和 0.81。研究确定整个区域非常容易发生故障，尤其是在下雨期间，因为孔隙压力的增加会降低斜坡形成材料的剪切强度。已根据山坡的不稳定性提出了可能的缓解措施。分别为 78 和 0.81。研究确定整个区域非常容易发生故障，尤其是在下雨期间，因为孔隙压力的增加会降低斜坡形成材料的剪切强度。已根据山坡的不稳定性提出了可能的缓解措施。
