A GENERAL FORMULATION TO DESCRIBE THE EMPIRICAL PREDICTION OF THE CRITICAL AREA OF A LANDSLIDE

Abstract

This study aims to find a general formulation for prediction of the critical area of a landslide through the analysis of the critical slip surface of embankment landslides in various conditions. This study uses several variables such as the typical soil subgrade and the embankment dimension. This research was conducted by the limit equilibrium method to obtain the value of the Safety Factor, circular centre, resistance moment, and several other landslide variables. The results obtained from this study show that the minimum landslide Safety Factor does not produce the largest amount of reinforcement requirements. In addition, the landslide area which produces the largest amount of reinforcing needs is different for each variable used. Empirical formulations were generated in this study to help construction designers to carry out reinforcement of road embankments to provide safety from landslides.
