SITUATION 3 Determine the height of the infinite slope, H, such that the factor of safety of 3.1 is
maintained against sliding along the soil rock surface. Slope is inclined at 15° with respect to the
horizontal, unit weight of soil is 20 kN/m³, cohesion is 47 kPa, and angle of friction is 33º.
SITUATION 4 If downward seepage occurs on the same slope from Situation 3, determine H. Specific
gravity of soil is 2.75, void ratio is 0.70, and the soil from situation I is assumed to be 50% saturated.
