The following is a collection from the writer's old exam files (with few additions for the occasion).
The question is True or False?
- Degree of saturation is the percentage of saturated samples obtained from the field.
- Active earth pressure occurs in active soils and passive earth pressure occurs in passive soils.
- Overconsolidation ratio (or OCR) is the fraction of samples that are excessively consolidated in the lab.
- The unconsolidated type triaxial tests, also known as the UU type, are performed on samples that are not preconsolidated in the field.
- Consolidation means solidifying together; it refers to the liquid phase turning solid and melding with the original solids in the soil. The concept should not be confused by a term defined in geology, which means soils turning into rocks (scary, isn't it?).
- Examples of active soils are San Fransisco Bay Mud and Boston Blue Clay, especially when active ingredients, such as sands and gravels, are added.
- Void Ratio is the remaining fraction of void samples left at a construction site in case a contract is declared void; it should be expressed as a fraction, not as a percentage.
- A factor of safety on shear strength should be applied in any situation when there is reasonable doubt that they don't know how to measure the shear strength in the lab.
- Consolidated type triaxial tests, like CU and CD, are done on samples that are not preconsolidated already.
- We say Trial failure surfaces when a court rules against a geotechnical engineer and this becomes obvious to everyone.
- Unconfined compression test is preferred by those who enjoy freedom so much that they despise confining anything.
- Correction factors should be applied on every single term of the bearing capacity equation because the theory is all wrong.
- An analytically oriented geotechnical engineer is one who has an analytical mind but doesn't have the courage to touch a soil sample---the fact is he/she couldn't get permission from his/her mother to play with dirt).
- An experimentally oriented geotechnical engineer is one that is still at an experimental stage---the fact is he did get permission from his mother, and he was able to figure out how to make a living playing with dirt!
- Specific Gravity refers to the gravity of the situation when soil properties are not specific enough.
- Two parties agreeing on how to solve their dispute out of court is called the settlement.
- Shrinkage Limit is to what extent one can lose weight.
- Geotechnical engineers are like wine; they get better with time.
Answer: All False
Note. The names of those individuals who have answered some of these questions as "True" that are currently in high places will be kept in strictest confidence.
