Lecture
This lecture covers the analysis of slope stability using the limit equilibrium method, focusing on circular failure surfaces in cohesive soils. The instructor explains the Kerisel Chart, which aids in determining the critical slip surface and factors of safety. The lecture also discusses the application of the method of slices and the consideration of effective stress in calculating the resisting moment. Various equations and diagrams are presented to illustrate the concepts, including the influence of water on slope stability and the generalization of circular failure surfaces for cohesive and frictional soils.
