A doubly drained soil specimen is 3 cm thick. It is loaded from 'v = 150 kPa
Question:
A doubly drained soil specimen is 3 cm thick. It is loaded from σ'v = 150 kPa to 300 kPa, leading to a change in void ratio from 1.30 to 1.18. Its original void ratio at the start of the test, eo = 1.42.
(a) If the time required for 50% consolidation is 20 min, what is the coefficient of consolidation, cv, of the soil in cm2/s?
(b) How much vertical strain occurs during the loading from 150 to 300 kPa?
(c) What is the coefficient of permeability for this soil, in cm/s, based on these results?
