The appropriate test for cohesion less soil is

The activity number range for an inactive soil sample is:

Which type of soil is suitable for the cultivation of Rubber and Cinchona?

The soils that are deposited by water at river beds are called

What is the difference between the water surface elevations in piezometers called?

The water content at which the soil changes from semisolid state to solid state is known as

Compute the total active earth pressure (in kN/ sq m; round - off to the nearest whole no. ) at a depth of 8m in dry cohesionless sand with friction angle (phi) 30 degrees and unit weight of 18 kN/cum.

The cell pressure is increased from 0.1 N/m² to 0.26 N/m², and the pore water pressure is increased from 0.07 N/m² to 0.15 N/m² in a triaxial test. What is the value of Skempton's pore pressure parameter?

According to Taylor, when an earthen dam with height H is filled with cohesive soil with cohesion C, unit weight of soil W, and factor of safety of soil Fc, then the stability number (Sn) is given as:

In the falling head permeability test, the length and cross - sectional area are 0.17 m and 21.8 x 10^-4 m² respectively. Calculate the time required (in s) for the head to drop from 0.25 m to 0.1 m. The area of cross - section of stand pipe is 2 x 10^-4 m². The sample has three permeable layers as -

K1 = 3 X 10^-5 m/s; H1 = 0.06 m

K2 = 4 X 10^-5 m/s; H1 = 0.06 m

K3 = 6 X 10^-5 m/s; H1 = 0.05 m thickness.

Assume that flow is taking place perpendicular to the bedding plane.
