Question 5
At the construction site, 4m thick clay layer is followed by 5m thick gravel layer which rest on an impervious rock. A surcharge of 20
is applied at surface. Saturated unit weight of clay is 18.5
and for gravel is 20
. If water table is at ground level, then the effective stress at the bottom____________ ![](https://gradeup-question-images.grdp.co/liveData/PROJ15825/1544523636049434.png)

Question 6
An embankment 6 m high is made of soil having effective stress parameter are c’ = 40 kN/m2 and φ’ = 15
and ϒ = 17.2 kN/m3. The triaxial test pore pressure parameters are A = 0.44 and B = 0.9. Calculate the shear strength of the soil (in kN/m2) at base of embankment after the fill has been raised by 3 m. Assume that the dissipation of pore pressure is negligible and at any point lateral pressure can be taken as one third of vertical pressure at that point.
