Clay layer A with single drainage and coefficient of consolidation Cv takes 6 months to achieve 50% consolidation. The time to layer B of the same thickness with double drainage and coefficient of consolidation \(\frac{{Cv}}{2}\) to achieve the same degree of consolidation.
Oedometer is used to calculate which of the following soil parameter
A clay layer of thickenss H has a preconsolidation pressure pc and an initial void ratio e0. The initial effective overburden stress at the mid-height of the layer is p0. At the same location, the increment in effective stress due to applied extrenal load is Δp. The comprssion and swelling indices of the clay are Cc and Cs, respectively. If P0 < Pc <(P0 + Δp), then the the correct expression to estimate the consolidation settlement (Sc) of the clay layers is
Consider the following statements:1. Secondary consolidation of soil follows Terzaghi’s one-dimensional theory of consolidation.2. Consolidation is a function of total stress.3. Even after complete dissipation of excess pore pressure, the soil undergoes a little more consolidation.Which of the above statements is/are correct?
In a consolidation test, when the load is changed from 50 kN/m2 to 100 kN/m2, then the void ratio changes from 0.80 to 0.60. The coefficient of compressibility will be:
For a particular loading Condition unsaturated clay layer undergoes 30% consolidation in a period of 180 days. What would be the additional time required for further 20% consolidation to occur
In a tri-axial test carried out on cohesion less soil sample with a cell pressure of 20 kPa, the observed value of applied stress at the point of failure was 40 kPa. The angle of internal friction of the soil is _________.
If the co-efficient of permeability is doubled and the co-efficient of volume compressibility is simultaneously haved, the co-efficient of consolidation

For finding out the time ‘t1’ required to achieve 50% consolidation of 1 m thick clayey strata resting on an impermeable rock at the bottom and sandy soil at top, a laboratory consolidation test was carried out, using 1 cm thick sample obtained from the same strata. Time “t12” was taken by it to achieve 25% consolidation, under double drainage conditions in the laboratory.Choose the correct value of the ratio \(\frac{t_1}{t_2}\) from the following:

A 1 m thick layer of saturated clay, drained at both faces, settles by 10 cm in one year. If a thin layer of prvious soil is introduced in the middle of this layer, then what will be the period during which the settlement of 10 cm will be compacted?
