Abstract: Landslide is a natural process and geomorphic development of a region. Human intervention often aggravates natural balance of an area resulting in Landslide. Systematic Stability investigations are essential to evaluate landslide hazard for successful implementation of such projects and finding out suitable control measure. To evaluate any large scale (1: 1000 to 2000) landslide hazards steps to be followed are: Preparation of topographical map & sections, Study of slope geometry of landslide, Geological study of slope materials, Study of geotechnical properties, Identification of possible causative factors, Identification of mode of failure- such as plane failure, wedge or rotational failure and Calculation of factor of safety (FOS) for stability status. The Ambuja Cements factory in Dharlaghat, in H.P (under construction) has been discussed as case study to elaborate these steps. Rocks exposed on slope are limestone; they are dislocated rock blocks, highly heterogeneous, contain many pockets of loose & low strength materials; and at places are of big size. Rocks show haphazard cracks, often indicating shearing along fracture planes; and there are several wet patches particularly within loose pockets. Overhangs at many places and weathering along fractures make the rocks more vulnerable. Both switchyard & Bulk loading are very important sites in any Cement factory and requires huge excavation of hill slope, 20- 35m near vertical excavation. Any instability of slope would result in high economic loss. The Geological and geotechnical considerations were examined only to find out that the slopes are unstable. Depending on the findings from the site observations rotational failure analysis for important sections have been chosen using computer program SARC. The Analysis has been done under dry, saturated & dynamic conditions. Accordingly controlling measures are suggested.
