Soil Stability and Slope Analysis of Landslides-A Review
Abstract
The movement of mass of a soil in a downward direction of a slope is called a slide or a slope failure. The failure of a natural slope is a common geological phenomenon occurring whenever an imbalance takes place between shear strength and shear stress in the ground. The first sign of an imminent landslide is the appearance of surface cracks in the upper part of the slope, perpendicular to the direction of the movement. The instability is either due to increase in seepage pressure, due to excavation of slope toe material, due to increase of shear stress from surface loading as a result of construction or train traffic. The slip may occur through the fill, through the base or through foundation. A number of design approaches are available. Design methods of analysis for determining the stability of gabion walls are based on The Code of Practice BS 8002. The two methods considered are:
• Serviceability Limit State Design.
• Ultimate Limit State Design.
