Challenge Problems
Push your limits with advanced challenges
You perform a DCPT and record the following penetration depths: 10mm, 12mm, 15mm, 14mm. Calculate the average penetration and discuss what this average might imply about the soil's strength.
💡 Hint: Think about how depth relates to strength.
In a project, the DCPT indicated weak soil, but a laboratory test afterward showed adequate strength. Discuss possible reasons for this discrepancy and how to handle such situations.
💡 Hint: Consider the nature of soil samples and field conditions.
