Abstract
The Chamba – Bharmour National Highway – 154A often gets affected because of landslide disaster. This study dealt with a slope failure geohazard assessment along the highway for the factor of safety (FOS) evaluation. A huge soil slope of circular failure type was recognized along the national highway (NH) at village Lothal near Trilochan Mahadev Temple. The adjoining features like hoses and penstocks for hydroelectric turbine are present at a few meter distances from the current slide. A geotechnical and morphological based slope stability analysis was performed after extensive field visits and laboratory testing. A finite element method using PLAXIS 2D simulator was applied to calculate FOS of the slope. The FOS based on finite element method was found to be equal to 0.975 in case of undrained slope and 1.093 in case of drained conditions. The slope stability determination should be practiced to ensure safe environment and for better disaster mitigated design.
