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?

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:
