Slope Stability Definition
Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement. ... Similarly, a slope can be locally stable if a safety factor larger than 1 is computed along any potential sliding surface running through a limited portion of the slope (for instance only within its toe). How do you determine stability of slope? Stability is determined by the balance of shear stress and shear strength. If the forces available to resist movement are greater than the forces driving movement, the slope is considered stable. A factor of safety is calculated by dividing the forces resisting movement by the forces driving movement. What factors affects slope stability? Five factors influence slope stability of an embankment: Shear strength of the soil Unit weight Embankment height; Slope steepness; and Pore pressure withi...
