Question 1.
What does SPT stand for?
Show hintHide hint
It is a commonly used field test.
Question 2.
What does the CPT measure?
Show hintHide hint
Consider what happens when you push an object into sand.
3Question 3.
What does SPT measure?
- Soil cohesion
- Number of blows to penetrate soil
- Moisture content
Show hintHide hint
Think about how resistance is measured in this method.
4Question 4.
CPT provides what kind of data profile?
- Discrete
- Continuous
- Both Discrete and Continuous
Show hintHide hint
Consider how data is represented in this method.
Question 5.
Explain how field tests (SPT, CPT, Vs) could impact the design of a bridge in a seismic zone. Consider various soil conditions and assessments of liquefaction risks.
Show hintHide hint
Reflect on how varying soil conditions can affect structure stability.
Question 6.
You conduct an SPT and record an N-value of 4 in a layer followed by a CPT indicating low resistance. What recommendations would you make for upcoming construction?
Show hintHide hint
Think about the implications of low resistance on safety measures.
