Given A vane field test was performed in a layer of soft clay. The vane tester had a diameter of 4.50 inches and height of 8.40 inches. The torque required to shear the clay was 209 in lb. Laboratory tests indicate that the clayey soil has a liquid limit of 50% and plastic limit of 10%. Required Determine the clay's cohesion in lb/ft², to the nearest 10th.

Transcribed Image Text:Given A vane field test was performed in a layer of soft clay. The vane tester had a diameter of 4.50 inches and height of 8.40 inches. The torque required to shear the clay was 209 in lb. Laboratory tests indicate that the clayey soil has a liquid limit of 50% and plastic limit of 10%. Required Determine the clay's cohesion in lb/ft2, to the nearest 10th. Your Answer:
Given A standard penetration test (SPT) was performed at a depth of 3.75 m below the ground surface in a silty sandy soil. Geotechnical tests show the unit weight to of the soil to be 20.72 kN/m³. The blow counts recorded using a 24 in. sampler were 13/19/26/16. Required Determine the corrected N-value using the N' method, to the nearest whole number. Your Answer:
