A Proposed Modeling Method in Finite Element Slope Stability Analysis
Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...

Rock Slope Stability Analysis Using Discrete Element Method
Rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). Since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. Also, Rock slope instability is a major hazard for human activities and o...
متن کاملA Comparison of Finite Element Slope Stability Analysis with Conventional Limit-equilibrium Investigation
In the assessment of slopes, factor of safety values still remain the primary indexes for determining how close or far slopes are from failure. Traditional limit-equilibrium techniques are the most commonly-used analysis methods. Recently, however, the significant computing and memory resources typically available to the geotechnical engineer, combined with low costs, have made the Finite Eleme...
متن کاملSlope stability analysis with FLAC and limit equilibrium methods
The factor of safety for slopes (FS) has been traditionally evaluated using two-dimensional limit equilibrium methods (LEM). However the FS of a slope can also be computed with FLAC by reducing the soil shear strength in stages until the slope fails. This method is called the shear strength reduction technique (SSR). Many authors have pointed out several advantages of SSR over the limit equilib...
