Depth: 4 m, Blow count (N): 15
Depth: 6 m, Blow count (N): 20
The energy ratio is 60%, and the overburden correction factor CN is 1.1. Calculate the
corrected N-values for each depth.
2. A soil sample was collected from a depth of 3 m using a Shelby tube. The sample had a volume
of 0.01 m³ and a mass of 18 kg. If the water content is 12%, calculate the (a) bulk density, (b) dry
density, and (c) void ratio of the soil. Assume the specific gravity of soil solids (Gs) is 2.65.
