A deposit of sand has porosity of 35% and G = 2.7. The soil is dry in top 1.5 m depth, it has 15% moisture content in next 1.8 m depth and it is submerged below it. Find : (i) Effective pressure at a depth of 8 m below the ground level. (ii) Change in effective pressure if the water table suddenly drops to a level of 6 m below the ground level. (iii) Shear strength of the soil on horizontal plane at 8 m depth for both the positions of ground water table if o=30°.
