Webthe soils may also be required. Although these methods define movements and stresses through-out the slope, they do not provide a direct measure of stability, such as the factor of safety calculated by limit equilibrium analyses. The focus in this chapter is on soil slopes and mechanisms involving shear failure within the soil mass. WebSoil–water characteristic curves and hydraulic conductivity functions are significant in the research of unsaturated soil seepage [4,5]. The normal method used for analyzing slope stability is confronted with some problems when analyzing natural slope problems. Many factors such as time and climate affect the stability of natural slopes. game 5 nights at freddy\\u0027s
