Solve Only Problem 8

Transcribed Image Text:7. A 6.0-m-high retaining wall with a vertical back retains a homogeneous saturated clay.
The specific weight of saturated clay is 1.90 ton/m3. Laboratory tests indicate that the
Undrained shear strength Cu of the clay is 1.71 ton/m2
a) Make the necessary calculations and draw the variation of the active Rankine pressure on
the wall with respect to depth
b)
Find the depth at which a tension crack can occur.
c) Determine the total active pressure per unit length of wall before a crack occurs. strain. Y
Determine the total active pressure per unit length of wall after the crack occurs. strain
d)
= 1.94 ton/m³
Y SAT
C = 1.71 ton/m²
$ = 0°
H = 6.0 m
