5 cards from this section. Quick, good the night before a test.
What does a triaxial test help determine?
Think about the contribution of the test to soil mechanics.
Name the three types of triaxial tests.
Recall the drainage conditions for each test.
What are the three categories of triaxial tests?
Recall the tests and conditions discussed.
The effective stress is defined as which of the following: σ' = σ - u?
Think about how we calculate effective stress.
A saturated clay sample is subjected to a consolidated-undrained test, yielding a total stress of 200 kPa with a pore water pressure of 75 kPa. Compute the effective stress and discuss its implications for soil stability.
Remember the effective stress equation.
If a horizontal Mohr’s circle in an unconsolidated-undrained test demonstrates a horizontal tangent line, explain what this implies about the shear strength under varying confining pressures.
Consider what happens to pore water pressure in saturation.
