A cantilever retaining wall is designed to retain the earth 5 m high behind the
wall. The unit weight of soil is 18 kN/m3 and angle of internal friction is 22°. The bearing capacity of soil is 130 kN/m2 and coefficient of friction between base and soil is 0.4. Use M20 ? Fe 415. Assume depth of foundation is as 1.0 m. Fix the dimension of retaining wall and design only stem. Also carry out stability checks.
