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 کاملspecialized methods to teach spelling: comparing three methods
چکیده: بررسی ادبیات مربوطه در کشور در زمینه یادگیری زبان انگلیسی نشان میدهد که علیرغم اهمیت املا در فرآیند یادگیری به طور عام و یادگیری زبان انگلیسی به طور خاص، این مولفه از جایگاهی متناسب با اهمیت آن برخوردار نیست و عمدتاً نادیده گرفته شده است. تحقیقات گستردهای در خارج از کشور در مورد ماهیت این مولفه صورت گرفته است، در حالی که به جرأت میتوان گفت در داخل کشور گامی در مورد درک ماهیت آن و فرآی...
15 صفحه اولA Review of Three-Dimensional Slope Stability Analyses based on Limit Equilibrium Method
The stability of slopes is a major concern in the field of geotechnical engineering. Usually two-dimensional analyses based on limit equilibrium method are implemented in this field due to their simplicity and effectiveness. Since these methods ignored the features of the third dimension of slopes, three-dimensional analyses have developed to remove this shortcoming. However, some limitations s...
متن کاملSlope Stability Analysis Using Limit Equilibrium Method in Nonlinear Criterion
In slope stability analysis, the limit equilibrium method is usually used to calculate the safety factor of slope based on Mohr-Coulomb criterion. However, Mohr-Coulomb criterion is restricted to the description of rock mass. To overcome its shortcomings, this paper combined Hoek-Brown criterion and limit equilibrium method and proposed an equation for calculating the safety factor of slope wit...
متن کاملpore water pressures in three dimensional slope stability analysis
although some 3d slope stability algorithms have been proposed in recent three decades, still role of pore pressures in three dimensional slope stability analyses and considering the effects of pore water pressure in 3d slope stability studies needs to be investigated. in this paper, a limit analysis formulation for investigation of role of the pore water pressure in three dimensional slope sta...
