Slope Stability Analysis and Suggestive Measures for an Active Landslide in Indian Himalaya

Abstract

Landslides are frequently occurring phenomena in Indian Himalayas causing considerable loss of lives and property every year. There are several active landslides along the major highways which pose recurring problems to the traffics particularly during the monsoon season. One such landslide has been studied in detail for planning and design of suitable control measures. The paper presents the geo-investigation and slope stability analysis carried out to arrive at suitable control measures. Geotechnical investigation and slope stability analysis were carried out to assess the present stability condition of the landslide. The results of the analysis have shown that the landslide is presently active and it needs suitable control measures to minimize the landslide activities. Soil nailing was one of the options found to be suitable for reinforcement of loose debris material on the uphill slope. It was observed that the stability of the slope significantly improves when soil nailing measure was considered.
