1.Indicate the incorrect statement. In a conventional consolidation test, the following
factors do not significantly affect the result:
(a) Moderate variation in room temperature
(b) Variation in pore fluid properties
(c) Variation in specimen size
(d) Variation in duration of load increment
2.
Assertion A:
Both
mv and
av decrease with increasing stress.
Reason R:
Both
mv and
av are influenced by the stress history.
Choose the correct codes.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, and R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
3. A sand exhibits considerable secondary compression due to
(a) High stresses (b) High pore water pressure
(c) Presence of less fines (d) Delayed consolidation 4. Explain why the measured values of time and rate of settlement do not agree with the predicted values.5. How do you estimate the field
e–p
curve of an over-consolidated clay ?
