A standard penetration test has been conducted on a coarse sand at a depth of 16 ft below the surface. The blow counts obtained in the field were as follows: 0-6 in. (4 blows), 6- 12 in. (6 blows), and 12-18 in. (6 blows). The tests were conducted using a USA-style donut hammer in a 6 in. diameter boring using a standard sampler with the liner installed. The vertical effective stress at the test depth was 1500 lb.ft'. Determine N1.

The blow counts for an SPT test at a depth of 6 m in a coarse-grained soil at every 0.152 m are 10, 10 and 10. A donut automatic trip hammer and a standard sampler were used in a borehole 152 mm in diameter. The SPT N value is: O 1.8 O 2.5 O 3.20 O 4. 10
A standard penetration test has been conduted at a depth of 15 ft in an 8-inch diameter exploratory boring using a USA-style safety hammer and a standard sampler. This test produced an uncorrected N-value of 12. The soil inside the sampler was a fine-to-medium sand with Dsq = 0.6 mm. The vertical effective stress at this depth is 1100 lb/ft². Adjust the N- value as described in Class handout, then compute the relative density and classify the soil using Table 3.3.
