Geotechnical Engineering MCQs Set-3

21. Coefficient of earth pressure at rest is

less than both the active and passive earth pressures

less than active pressure but greater than passive earth pressure

greater than both the active pressure and passive earth pressure

greater than active earth pressure but less than passive earth pressure

22. The slope of isochrone at any point at a given time indicates the rate of change of

pore water pressure with time

pore water pressure with depth

effective stress with time

effective stress with depth

23. The admixture of coarser particles like sand or silt to clay causes

increase in both liquid limit and plasticity index

decrease in liquid limit and no change in plasticity index

decrease in liquid limit and increase in plasticity index

decrease in both liquid limit and plasticity index

24. Coefficient of consolidation for clays normally

decreases with increase in liquid limit

first increases and then decreases with increase in liquid limit

remains constant at all liquid limits

increases with increase in liquid limit

25. If the permeability of a soil is 0.8 mm/sec, the type of soil is

silt

gravel

sand

clay

26. Which of the following methods is most accurate for the determination of the water content of soil?

oven drying method

pycnometer method

sand bath method

calcium carbide method

27. Effective stress is

important because it is a function of engineering properties of soil

all of these

a physical parameter that can be measured

the stress at particles contact

28. If the water table rises upto ground surface, then the

effective stress is reduced due to increase in pore water pressure only but total stress does not change

effective stress is reduced due to decrease in total stress only but pore water pressure does not change

total stress is increased due to decrease in pore water pressure but effective stress does not change

total stress is reduced due to increase in pore water pressure only but effective stress does not change

29. Physical properties of a permeant which influence permeability are

viscosity only

unit weight only

both viscosity and unit weight

none of these

30. Void ratio of a soil mass can

take any value greater than zero

take values between 0 and 1 only

be zero

never be greater than unity
