GEO-5 Based Landslide Susceptibility Assessment of National Highway 66 From Mahad to Mangaon, Maharashtra, India

Abstract

A landslide can be defined as the movement of the mass of rock, debris, or earth down the slope. Environmental impacts including heavy rainfall in study area affects several sectors of the Mahad-Mangaon region, triggering many major and minor landslides and causing severe loss. Slope stability is the process of calculation an assessment of the required stress a particular slope managed before the failure criteria. GEO5 software determines the factor of safety of the desired slopes. The aim of this project is to determine the slope stability of the region belonging to the Ghat sections of Sahyadri mountain region of Maharashtra mainly from NH-66Mahad to Mangaon (27km) using Geo5software. Factors including the soil cohesion, angle of internal friction, and unit weight of soil is determined using the lab experiments. Total station surveying is done to obtain the coordinators of the study area
which is used as input for the Geo5 software.
