Question 1.
What happens to pore water pressure under cyclic loading?
Show hintHide hint
Think about how water behaves in saturated soils during shaking.
Question 2.
What is effective stress?
Show hintHide hint
Consider this as the total stress you need to take into account when the soil is saturated.
3Question 3.
What is the primary effect of cyclic loading on pore water pressure?
- Decreases the pressure
- Increases the pressure
- Has no effect
Show hintHide hint
Remember how water moves in response to external forces.
4Question 4.
True or False: Effective stress increases when pore water pressure increases.
- True
- False
Show hintHide hint
Refer to the definitions of effective stress.
Question 5.
Evaluate how the increase in pore water pressure contributes to ground failures during a specified historical earthquake.
Show hintHide hint
Refer to historical accounts and data from geological surveys.
Question 6.
In a hypothetical scenario where ground improvements are neglected in a liquefiable soil area, predict the outcomes during a significant seismic event.
Show hintHide hint
Consider what factors could fail without proper engineering solutions.
