Slope Stability Analysis Using Numerical Method

Abstract

Stability evaluations are regularly achieved in order to measure the safe and efficient design of man-made slope (e.g. open pit mining, road cuts, etc.), and/or the stability conditions of a natural slope. It has been issue of concern to numerous previous investigators. The numerical technique chosen depends on both soil specifications and its situations and the potential mode of failure. Assessment has been made for slope system with different slope for both cohesive and cohesionless soil. Two-dimensional finite element approach has been used to simulate and analysis the whole geotechnical system. This study illustrated that the factor of safety in the structure of slope case decreased while the slope was increasing for both types of soils. In addition, the displacement in the points when the section is change (in the critical zone) is increasing when the slope is increasing.
