A retaining wall having a smooth vertical back retains a soil
mass for a depth of 9 m. The soil has the following properties: cu
= 34 kPa; u= 0º; γ = 18kN/m3 . Assume groundwater table is well
below the base of the retaining wall and NO rainwater in the
tension crack.
Calculate the depth of tension crack (in m).
Calculate the resultant active thrust (in kN/m)
Calculate the point of application from base (in
m).
