Consider the following statements: 

1. Organic matter decreases the permeability of a soil. 

2. Entrapped air decreases the permeability of a soil. 

Which of these statements are correct? 

Statement (I): Consolidation is the process of expulsion of pore water by applying steady load

for a long time.

Statement (II): Volume change occurs immediately after the action of the load in case of

consolidation tests. 

Statement (I): Cohesion and angle of internal friction are shear strength parameters of soils.

Statement (II): Cohesion is zero for pure sand and angle of internal friction is zero for pure clay. 

Assertion (A): The state of earth pressure at rest is the state of equilibrium with zero strain

condition. 

Reason (R): In rest condition neither the wall nor the soil moves.

for at-rest condition, compare as:

Statement (I): Foundations may not be geometrically categorized as shallow, or deep,\

foundations.

Statement (II): A foundation is shallow if its depth is equal to or less than its width; otherwise it is

deep.

same pressure will be: 

A compacted clayey sample with drainage at each end is to allowed to fully consolidate in a

triaxial shear test apparatus under a cell pressure of 100 kN/m². The cell pressure is then

increased to 250 kN/m² and an increase in pore water pressure of pressure of 130 kN/m²

is recorded. The value of Skempton's pore water pressure  parameter, B is 

Match List-I with List-II on the basis of Terzaghi's one dimensional consolidation theory and

select the correct answer using the codes given below the lists (Notations have their usual

meaning).

A masonry dam 100 m long and overlying an impervious soil is founded on a soil with anisotropy

in permeability. The upstream water level is 12.5 m and the tail water level is 3.5 m above the

ground level. The vertical permeability of the soil is 1.40 m/day and the horizontal permeability is

9 times as that of the vertical permeability. The flow net drawn on a transformed section yields 6

flow channels and 8 equipotential drops. The seepage through the foundation soil, per 'm' length

of the dam is
