Bearing capacity from field tests

What this module covers

• Correct a raw SPT blow count to N₆₀ and (N₁)₆₀ and say what each correction removes
• Derive a friction angle from corrected SPT data and carry its uncertainty forward
• Estimate undrained strength from CPT data and identify the judgement in the cone factor
• Explain why correlated parameters demand a sensitivity check rather than a single answer

Lessons

1. 8.1

   From blow count to bearing pressure

   Four corrections, one correlation, and an exponential.
