Geotechnical Engineering MCQ with Answers

96) Select the incorrect statement.

Answer is:

Unconfined compression test can be carried out on all types of soils.

97) If the shearing stress is zero on two planes, then the angle between the two planes is

Answer is:

90°

98) In the triaxial compression test, the application of additional axial stress (i.e. deviator stress) on the soil specimen produces shear stress on

Answer is:

all planes except horizontal and vertical planes

99) In a triaxial compression test when drainage is allowed during the first stage (i. e. application of cell pressure) only and not during the second stage (i.e. application of deviator stress at constant cell pressure), the test is known as

Answer is:

consolidated undrained test

100) During the first stage of triaxial test when the cell pressure is increased from 0.10 N/mm2 to 0.26 N/mm2, the pore water pressure increases from 0.07 N/mm2 to 0.15 ″N/mm2. Skempton′s pore pressure parameter B is
