Question 1

A fill having volume of 1500m3 is to be constructed at a void ratio of 0.6. The borrow pit soil has void ratio of 1.2. What volume of soil (cubic metres) should be extracted from the borrow pit for the construction of fill?

Question 2

The ground conditions at a site are:

Water table is at ground level.

Water content = 20%

Specific gravity = 2.6

Unit weight of water = 10 kN/m2

Then effective stress, at a point 4 m below ground level is
