3 cards from this section. Quick, good the night before a test.
What does the triaxial test primarily measure?
Think about what we evaluate during soil testing.
Name one type of triaxial test.
We mentioned three specific types.
What is the primary purpose of the triaxial test?
Focus on the aspect of soil behavior we observe during the test.
The Consolidated-Undrained test does not allow for drainage. Is this statement True or False?
Remember what happens during this testing process.
You are given a clay sample with a known pore water pressure parameter A = 0.65. If the confining pressure σ3 is 100 kPa and you apply an axial stress resulting in a difference of σ1 - σ3 = 50 kPa, calculate the pore water pressure during the test.
Pay attention to how A influences pore water pressure.
Consider a soil with cohesion (c) of 25 kPa and angle of internal friction (ϕ) of 30 degrees. Using Mohr’s Circle, describe how to find the maximum shear stress at failure.
Recall how the geometry of Mohr’s Circle relates to the stresses involved.
