Determine the factor of safety, Fs, for the infinite slope shown in Figure 15.47, where seepage is occurring through the soil and the groundwater table coincides with the ground surface. Given: H = 6 m, β = 22°, γsat = 20.8 kN/m3, ϕ = 26 ° , and c′ = 52 kN/m2.


Figure 15.47

To determine

Find the factor of safety Fs for the infinite slope.


Given information:

The slope rise at an angle β with the horizontal line is 22°.

The saturated unit weight γsat of the soil is 20.8kN/m3.

The height (H) of the soil is 6 m.

The angle of friction ϕ is 26°.

The cohesion c is 52kN/m2.


Determine the submerged unit weight γ of the soil using the relation.


Here, γw is the unit weight of the water.

Take the unit weight of the water as 9.81kN/m3.

Substitute 20.8kN/m3 for γsat and 9.81kN/m3 for γw.
