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.

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:
Transcribed Image Text: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.
