Question

A smooth vertical wall 4m retains cohesive soil backfill with C= 10KN/m square, pie=0 and gamma= 18KN/m square. Determine
1) the depth at which active earth pressure is zero.
2) depth of tension crack
3) depth at which total active thrust is zero.
4) plot of active pressure distribution.
5) total active thrust per unit length of Wall when tension cracks not developed. ​

Answer 1

Explanation:

ADVERTISEMENTS: Equation (15.8) indicates that the active earth pressure is zero at the top surface of the backfill (h = 0) and increases linearly with depth below the surface. The distribution of active earth pressure
