Question 1
A retaining wall 8 m high with a smooth vertical back retains clay with c = 15 KN/m2 , f = 15° and γ = 15 KN/m3. The magnitude of pressure at the top will be equal to? [Take sin 15° = 0.25]
Question 2
The total active thrust on a vertical wall 3 m height retaining a horizontal sand backfill (unit weight = 18 KN/m3, angle of shearing resistance = f’ = 30°) when the water table is at the bottom of wall will be?
Question 3
The earth pressure behind a bridge abutment is:
Question 4
Consider the following statement about Coulomb earth pressure theory:
1) It is valid for gravity type retaining wall.
2) Coulomb considered wedge failure and failure surface passes through the toe of the wall.
3) Wedge acts as a rigid body.
4) This theory is not suitable for passive earth pressure.
5) Coulomb considered elemental failure.
Which of these is/are correct?
