Question
Transcribed Image Text:A granular soil has y = 19 kN/m2, o' 35°. A slope has to be made of this material.
If a factor of safety of 1.3 is needed against slope failure, determine the safe angle of
slope (i) when the slope is dry or submerged without seepage, (ii) if seepage occurs
at and parallel to the surface of the slope. (iii) If seepage occurs parallel to the slope
with the water table at a depth of 1.5 m, what is the factor of safety available on a slip
plane parallel to the ground surface at a depth of 4 m? Assume B = 28°,
