If seepage forces are not acting on the soil, stability of infinite slope in a cohesion less soil is affected by-
-
Solution
Maximum inclination in a cohesion less soil in infinite slope is equal to angle of internal friction. Stability is affected neither by the unit weight of soil nor by water content.
