A standard penetration test was performed in a 150 mm diameter boring at a depth of 9.5 m be-low the ground surface. The driller used a UK-style automatic trip hammer and a standard SPT sampler. The actual blow count, N, was 19. The soil is a normally consolidated fine sand witha unit weight of 18.0 kN/m3 and D50 = 0.4 mm. The groundwater table is at a depth of 15 m. Determine the following:a. N60b. N1,60c. Drd. Consistency (based on Table 3.3)e. f′

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.

Please solve this problem and explain each step clearly, Please explain the theory and show your work clearly, I really want to understand. Thank you

A Cone Penetrometer Test (CPT) produces a continuous record of tip and sleeve resistance as well as pore pressure induced behind the cone tip. At a certain depth, the following are recorded: Cone Tip Resistance = 17 tsf; Friction Ration (Rf) = 2.6% The soil is most likely a O a Clayey Sit Ob Clay Sand Od Silt
