ABSTRACT
Example 10.3 Find the factor of safety of a slope of infinite extent having a slope angle = 25°. The slope is made of cohesionless soil with l/J = 30°.
Solution Factor of safety
F = tan f/J' = tan 30° = 0.5774 =1.238 s tanfJ tan 25° 0.4663
Example 10.4 Analyze the slope of Example 10.3 ifit is made of clay having c' = 30 kN/m2, l/J' = 20°, e = 0.65 and Gs = 2.7 and under the following conditions: (i) when the soil is dry, (ii) when water seeps parallel to the surface of the slope, and (iii) when the slope is submerged.
