Slope 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...
متن کاملInvestigation of Bishop’s and Janbu’s Models Capabilities on Slope Stability Problems with Special Consideration to Open-Pit Mining Operations
One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...
متن کاملEvaluation of the Strength and Deformation Parameters of Olimag Synthetic Olivine
Over the past decade, two buried pipe test cells have been developed by Brachman, Moore and others to evaluate the behaviour of buried pipes under various loading conditions. Health concerns have meant the use of silica-based materials in these cells has been discontinued, being replaced with Olimag synthetic olivine, a uniform angular material used for sand blasting. This paper classifies the ...
متن کاملComparison Analysis among Different Calculation Methods for the Static Stability Evaluation of Tailing Dam
The static stability evaluation of tailing dam is one of the most important tasks in the mine environmental protection project. The methods for the static stability calculation were discussed in this paper, which were Swedish Circle Method, Janbu Method, Bishop Method, Finite Element Method and Strength Reduction Finite Element Method (SRFEM) with five different failure criterions considered. T...
متن کاملLimit Equilibrium Analysis of the Influence of Matric Suction on Unsaturated Soil Slope Stability
In slope engineering, soils are commonly at unsaturated state. The question of how to apply unsaturated soil mechanics theory to the slope stability analysis has become a hot spot in today’s geotechnical engineering research. Based on the experimental research of how shear strength of residual soil varies with water content, reasonable computation modules can be created. By using limit equilibr...
