Slopes can be natural or manmade slopes. There are two aspects to slope stability: the safety against failure and the movement under normal conditions. The infinite slope is a case of a plane surface. The seepage force is the force exerted in friction by water flowing around soil particles and trying to drag them away. Tensile cracks can develop at the top of a slope due either to impending failure or to desiccation. When the soil is uniform and a circular failure surface is assumed, the problem is simple enough that the factor of safety can be determined from charts. The water stress along the bottom of the failure surface has a significant influence on the factor of safety. An added complexity in selecting the shear strength to use in the failure analysis occurs when the soil exhibits strain‐softening behavior. The finite element method can be used to analyze the stability of slopes.
