Question
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 with
a 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:
