AE-JE Foundation CE: Soil Mechanics Quiz 3

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?

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

A river 6 m deep consists of a sand bed with saturated unit weight of 21 kN/m³, = 9.81 kN/m³. The effective vertical stress at 4 m from top of the sand bed is

The permeability of a soil sample will be ______ if entrapped air is present in the sample:-

In a Soil deposit of three layers of equal thickness, the permeabilities of first, second and third layers are in the ratio 1:2:3 . The ratio of average permeability in horizontal direction (K_h) to that in the vertical direction (K_v) will be:

In laboratory, coefficient of permeability of soil is determined by one of the following methods:-
