Geotechnical analysis of slopes and landslides: achievements and challenges

PRIMARY OBJECTIVES Design Safe Slopes, Understand Performance of Slopes and Earth Dams, Quantify Landslide Susceptibility, Hazard and Risk, Landslide Risk Management, Reduction of Disaster Risk ESSENTAIL INFORMATION REGIONAL---Geology, Topography, Urbanisation, Landslide History, Triggering Factors(Rainfall ,Earthquakes etc) SITE-SPECIFIC----Soil and Rock Types, Discontinuities ,Pore Water Pressures, Shear Strength Parameters, Unsaturated Zones, Observed Slope Movements, Quality of Data IMPORTANT STEPS Identify Failure Mechanisms, Develop Geotechnical Models, Parameter Variability, Systematic Uncertainties, Assess Stability/Reliability/Hazard /Risk, Validate with Respect to Observed Data
