a 7m thick clay layet in the fiels drained on one side ( is normally consolidated ) when the pressure is increased from 60 kn/m^2 to 130kn/m^2 the void ratio decreaes from 1.12 to 0.98 the hydraulic conductivity ( cofficent of permeability ), k of clay during the above loading range was found to be 4.3 * 10^-7 cm/sec , how long in days will it take for clay to reach70% consolidation?

Consider a clay layer that is 1 m thick. The clay has a compression index of 0.35, a swell index of 0.07, a permeability of 4 x 10-7 cm/sec, a preconsolidation pressure of 172 kPa and a coefficient of consolidation of 2.7 x 10-4 cm2/min. The initial effective stress at the midpoint of the layer is 140 kPa, and the soil has a void ratio of 1.01. The stress is increased to 200 kPa. The soil is drained above and...

A 3-m thick, doubly drained saturated stratum of clay is under a surcharge loading that underwent 90% primary consolidation in 75 days. The coefficient of consolidation Cv of this clay in cm2/sec is most nearly equal to Select one: a. 0.00294 b. 254.01 c. 4.236 d. 0.294
During a consolidation test, a sample of fully saturated clay 3 cm thick is consolidated under...
During a consolidation test, a sample of fully saturated clay 3 cm thick is consolidated under a pressure increment of 200 kN/m2 . When equilibrium is reached, the sample thickness is reduced to 2.60 cm. The pressure is then removed and the sample is allowed to expand and absorb water. The final thickness is observed as 2.8 cm and the final moisture content is determined as 24.9%. If the specific gravity of the soil solids is 2.70, find the void...

The ultimate consolidation of a 13-ft thick single-drained clay layer (cv = 0.1 ft2/day) was calculated to be 0.813 feet. a. What is the average degree of consolidation for the clay layer when the settlement is 2 inches? b. If the average value for cv for the pressure range is 0.003 cm2/second how long will it take for 50% settlement to occur? (be careful on the units) c. If the 17 ft clay layer is drained on one side, how...

Consider a 20 foot thick saturated clay that has a sand layer above it and an impermeable rock layer below it. The clay layer has an initial effective stress at its midpoint of 3145 lbs/ft2.    Due to the presence of a large water tank on the surface, the stress is increased by 710 lbs/ft2 at the midpoint of the clay layer. How much total settlement from primary consolidation is expected? Provide your answer in inches. Soil properties: Compression index = .324,...
