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.

Expert Solution
Step 1

Given-

Standard penetration test SPT-

Depth d=3.75 m,

Unit weight of soil = 20.72 kN/m3,

Blow counts = 13, 19, 26, 16.

 

It is needed to find the corrected N value using N'-method.
