PROPOSED ANALYTICAL MODEL OF THE FAILURE SURFACE OF A LANDSLIDE IN COHESIVE SOILS BASED ON THE MASLOV MODEL

The paper presents a proposed method for determining the failure surface of a landslide based on Maslov?s method. Maslov?s approach defines the stable slope inclination by accounting for the additional apparent stability provided by cohesion, compared with the infinite-slope model for a cohesionless soil mass. The original formulation considers a uniform slope and relates the stable inclination to the maximum stress acting at the toe of the soil mass. However, when Maslov?s equation is applied progressively from t...
