The figure shows an element of soil at the interface between two dry sand layers on a =34 34 slope.

The figure shows an element of soil at the interface between two dry sand layers on a α=34

34° slope.

The interface is d=6

6 m below the ground surface and for both sand layers the friction angle is φ=30

30° and Ko = 0.42

0.42. Assume that the shear stress is zero on both the vertical and horizontal planes. 

γd1 (dry unit weight of sand layer 1) = 18

18 kN/m3

γd2 (dry unit weight of sand layer 2) = 19

19 kN/m3
