Solution

The correct option is A 1 and 2
During primary consolidation degree of saturation = 100% and void ratio reduces. There are no air voids in the soil i.e., it does not depend on the decrease in void volume due to air escape. During secondary consolidation only plastic deformation occurs.

Q. In the consolidated drained test on a saturated soil sample, pore water pressure is zero during

A layer of normally consolidated, saturated silty clay of 1.2 m thickness is subjected to one dimensional consolidation under a pressure increment of 25 kPa. The properties of the soil are: Specific gravity = 2.7. natural moisture content = 40% and compression index 0.45. The initial average effective stress within the layer is 125 kPa. Assuming Terzaghi s theory to be applicable, the primary consolidation settlement is mm

Q. If

Δ p

is increment of pressure on a normally consolidation saturated soil mass, as per Terzaghi's theory at the instant of application of pressure increment i.e., when time t = 0, what is the pore pressure developed in the soil mass?

Q. Directions : Each of the next items consists of two statements, one labelled as the 'Statement (I)' and other as 'Statement (II)'. Examine these two statements carefully and select the answers to these items using the codes given below:

Codes :

Statement (I) : Rate of settlement of a consolidating layer depends upon its coefficient of consolidation, which is directly proportional the permeability and number of drainage paths available.

Statement (II) : The excess hydrostatic pore pressure is relieved fast in soil of higher permeability, in turn, depending on the number of drainage paths available in the consolidating layer.
