- A long slope is formed in a soil with shear strength parameters: c’ = 0 and ϕ’ = 34⁰. A firm stratum lies below the slope and it is assumed that the water table may occasionally rise to the surface, with seepage taking place parallel to the slope. Use ϒsat = 18 kN/m3 and ϒw = 10 kN/m3. The maximum slope angle (in degrees) to ensure a factor of safety of 1.5, assuming a potential failure surface parallel to the slope, would be most nearly equal to?A long natural slope in an over-consolidated clay (c'=10kPa, φ'=25deg, γsat=20kN/m3) is inclined at 10 degrees to the horizontal.
