Que.5 A long natural slope in overconsolidated fissured clay of saturated unit weight 22kN/m³, is inclined at 14 degrees to the horizontal. The water table is at the surface and seepage is approximately parallel to the slope. A slip surface has developed on a plane parallel to the surface at a depth of 4m. Determine the factor of safety along the slip plane using the residual strenght parameter, 'r=20 degrees.

Que.5
A long natural slope in overconsolidated fissured clay of saturated unit weight 22kN/m³, is
inclined at 14 degrees to the horizontal. The water table is at the surface and seepage is
approximately parallel to the slope. A slip surface has developed on a plane parallel to the
surface at a depth of 4m. Determine the factor of safety along the slip plane using the residual
strenght parameter, o'r=20 degrees.
