Question

Which one of the following is the appropriate triaxial test to assess the immediate stability of an unloading problem, such as an excavation of a clay slope?

• A. UU test
• B. CU test
• C. CD test
• D. Unconsolidated drained tests

Answer 1

The correct option is A UU test

For problems of short term-stability of foundations; excavations and earth dams UU (Unconsolidated Undrained) tests are appropriate. For problems of long-term stability either UU test or CD test is appropriate, depending upon the drainage conditions of soil.
