| Abstract: | Slope instability problems at Agrakhal on Rishikesh-Uttarkashi-Gangotri National Highway of Uttarakhand State has
induced distress in many houses situated on the slope. Geological and geotechnical investigations were carried out to assess the slope
instability and risk assessment. Topographic survey of the slope was carried out and a contour map was prepared for topographic
analysis. Geologically the rocks present in the area are highly weathered phyllites. The outward dipping discontinuity in the rocks
favour slope instability. From the field investigation it is inferred that continuous water flow in a drain and water seepage at various
locations are the main contributing factors for the instability. Soil samples were collected and tested in the laboratory for their
geotechnical engineering properties. The paper presents the details of site investigation and slope stability analysis and risk
assessment. |
