The correct order of the steps of a laboratory undrained unconsolidated (UU) triaxial test is,
a. Sample placement and setting of the pressure cell
b. Shearing by loading vertically
c. Application of confining pressure
d. Close the drainage valve
State whether the below statement is True or False.
In unconsolidated undrained (UU) tests, the peak stress does not depend upon the confining pressure (σ3).
What would happen if you keep the drainage valve open during the triaxial test?
a. Consolidation process will begin
b. Vertical load will continuously increase without causing a sample failure
c. Test will automatically stop
d. The excess pore-water inside the sample will drain out gradually during the test
State whether the below statement is True or False.
In unconsolidated undrained (UU) tests, we do not consolidate the sample or allow pore water pressure dissipation when we apply the confining pressure or when we apply the axial load (shearing)
Out of the followings, what is not an objective of conducting a triaxial test?
Which of the following statement is correct?
i. Soil liquefaction occurs when a saturated or partially saturated soil substantially loses strength and stiffness
ii. Liquefaction can happen due to earthquake shaking or other rapid loading
iii. Saturated clay or silty clay are highly susceptible for liquefaction.
Which of the following is not a geohazard/ critical geotechnical consideration associated with Coodeisland silt?
Which of the following geological sequence is correct for the Melbourne CBD area? (Top layers indicate young material and bottom layers indicates older materials)
Which of the following statement is correct?
i. Most local councils of Victoria have inventory of landslide susceptible areas.
ii. Aerial photographs and geomorphological mapping can be used to understand landslide susceptible areas.
iii. In Victoria most landslides are triggered by increasing the water pressure.
State weather following statement is true or false.
One of the key mechanisms of landslides in Victoria is, slope failures of chemically and mechanically weathered rocks.
