Q:

The equation for the unconsolidated un drainage strength of clay is __________

A) τ = c + σ tan φ B) τf = ccu + σ tan φcu
C) τ = c + σ D) τ = σ tan φ
 
Answer & Explanation Answer: B) τf = ccu + σ tan φcu

Explanation: The equation for consolidated undrained strength of the preconsolidated clay in terms of total stress can be approximately expressed as τf = ccu + σ tan φcu where, σ is the normal pressure.

Q:

Negative pore pressure in clay or sand is developed due to __________

A) Expansion on loading B) Over loading
C) Loose structure D) Compaction
 
Answer & Explanation Answer: A) Expansion on loading

Explanation: A negative pore pressure is developed when we apply load on a sample of clay or sand because both sand and clay tends to expand on loading.

Q:

Which of the following cannot be obtained by using un-drained test?

A) Effective stress failure envelope B) Shear strength
C) sensitivity D) All of the mentioned
 
Answer & Explanation Answer: A) Effective stress failure envelope

Explanation: Since only one Mohr circle in terms of effective stresses, is obtained from all un-drained tests, effective stress failure envelope cannot be obtained from this test.

Q:

The consolidated-un drained test can be performed in ___________ methods.

A) 3 B) 2
C) 4 D) 1
 
Answer & Explanation Answer: B) 2

Explanation: The consolidated-undrained tests are performed by two methods: i) the remoulded specimens are sheared under a cell pressure. ii) the moulded specimens are consolidated under the same cell pressure and sheared with different cell pressure.
