Estimate the vertical coefficient of permeability for a uniform clay deposit where representative test results are as shown: LL = 92, PL = 34 percent of clay size particles in the  soil =40 void ratio ( approximate ) = 1.75
The results of two consolidated drained test tri axial tests on a clay are given below specimen 1: chamber pressure = 105 deviator stress = 220   specimen 2: chamber pressure = 210 deviator stress = 400   1. determine the angle of internal friction 2. determine the cohesion of clay 3. determine the normal stress on the point on the failure plane of the 2nd specimen
Estimate the coefficient of permeability for a sand formation, given the following representative information. The representative void ratio value is based on calculations using results of in-place density tests and laboratory tests for the specific gravity of soil particles. The particle size data from grain-size-distribution analyses is: Void ratio e = 0.65, D60 = 2.0 mm, D10 = 0.40 mm

  • The figure below shows a 20 m thick layer of normally consolidated clay (ϒt = 18.6 kN/m3) that is one-dimensionally loaded by Δσv = 60 kPa. The clay layer is below a 5 m thick layer of granular fill (ϒt = 19.6 kN/m3), and a dense, compacted glacial till underlies the clay. The water table is located at the top of the clay layer. A 1-D consolidation test is performed on a 3.00 cm thick, doubly drained specimen from the middle of the clay layer. When the stress conditions from the field (including the Δσv = 60 kPa) are applied to this specimen, it takes 1.5 minutes for 60% average consolidation to occur.a. From the lab test data, determine cv for the soil.b. Compute pore water pressure at 20 m depth 7 years after the Δσv is applied to the clay layer. c. Compute the average degree of consolidation 7 years after Δσv application.
    The figure below shows a 24 m thick layer of normally consolidated clay (ϒt = 18.6 kN/m3) that is one-dimensionally loaded by Δσv = 100 kPa. The clay layer is below a 4 m thick layer of granular fill (ϒt = 19.6 kN/m3), and a dense, compacted glacial till underlies the clay. The water table is located at the top of the clay layer. A 1-D consolidation test is performed on a 2.50 cm thick, doubly drained specimen from the middle of the clay layer. When the stress conditions from the field (including Δσv = 100 kPa) are applied to this specimen, it takes 6 min for 90% average consolidation to occur.a. From the lab test data, determine cv for the soil.b. Compute the pore pressure at depth 22 m before and immediately after the 100 kPa stress is applied.c. At depth 22 m, compute the pore pressure 8.5 years after the 100 kPa is applied.
    Consider the soil profile shown in Figure 11.44 subjected to the uniformly distributed load, Ds, on the ground surface. Given: Ds = 26 kN/m2; H1 = 1.83 m; H2 = 3.66 m; and H3 = 5.5 m. Soil characteristics are as follows: Sand: gdry =17.9 kN/m3; gsat =18.5 kN/m3 Clay: gsat =18.3 kN/m3 ; LL = 38; e = 0.73; Cs = 1/5 Cc Estimate the primary consolidation settlement in the clay if The clay is normally consolidated The preconsolidation pressure s’c = 105 kN/m2
