Which of the following statements apply for slope stability (select all correct answers)? a)The driving forces acting along a slip surface increase as the soil unit weight below the slip surface increases and vice versa. b)A FoS equal to one is generally considered as safe in engineering practice when considering permanent actions. c)For coarse-grained soils, the FoS decreases as the soil friction angle decreases and vice versa. d)For non-saturated coarse-grained soils, the soil strength mobilised along a slip surface increases as the slip inclination angle decreases and vice versa. e)Planar slip surfaces are more likely to occur in saturated homogeneous clays in undrained condition.
