The soil profile at a site consists of 10 m of gravelly sandunderlain by a soft clay layer. The water table lies 1 m belowthe ground level. The moist and saturated unit weights of thegravelly sand are 17.0 kN/m3 and 20.0 kN/m3, respectively.Due to some ongoing construction work, it is proposed tolower the water table to 3 m below the ground level. Whatwill be the change in the effective stress on top of the softclay layer?

Question
The soil profile at a site consists of 10 m of gravelly sand
underlain by a soft clay layer. The water table lies 1 m below
the ground level. The moist and saturated unit weights of the
gravelly sand are 17.0 kN/m3 and 20.0 kN/m3, respectively.
Due to some ongoing construction work, it is proposed to
lower the water table to 3 m below the ground level. What
will be the change in the effective stress on top of the soft
clay layer?
