A very wide embankment 5 m high is constructed from a fill with a unit weight of 16 kN/m3 over a saturated sand deposit with the presence of water table coinciding with its top surface. At a depth of 3 m below the top surface of the sand deposit, determine the following: (a) total and effective vertical stresses before construction of the embankment, (b) increase in vertical stress induced by the construction of the embankment, and (c) total and effective vertical stresses after construction of the embankment. Assume the saturated unit weight of the sand is 20 kN/m3.
