A granular soil has G = 2.70, e = 0.5 and o = 35°. A slope has to be made of this material, It a tactor of safety of 1.15 is needed against failure, determine the safe angle of slope when (a) The slope is dry or submerged without seepage. (b) If seepage occurs at and parallel to the surface of the slope. (c) 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 i = 30°.
