Geotechnical Engineering MCQs Set-3

21. Compressibility of sandy soils is

much less than that of clayey soils

much greater than that of clayey soils

none of these

almost equal to that of clayey soils

22. Allowable bearing pressure for a foundation depends on

allowable settlement only

both allowable settlement and ultimate bearing capacity

ultimate bearing capacity of soil only

none of these

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

decrease in both liquid limit and plasticity index

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

24. Rise of water table above the ground surface causes

decrease in pore water pressure but increase in total stress

equal increase in pore water pressure and total stress

increase in pore water pressure but decrease in total stress

equal decrease in pore water pressure and total stress

25. The value of compression index for a remoulded sample whose liquid limit is 50% is

0.28

0.028

0.036

0.36

26. A combined footing is generally used when

number of columns is more than two and they are spaced far apart

there is only one column

number of columns is two and they are spaced close to each other

number of columns is two and they are spaced far apart

27. Void ratio of a soil mass can

take values between 0 and 1 only

take any value greater than zero

be zero

never be greater than unity

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

sand bath method

pycnometer method

calcium carbide method

oven drying method

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

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

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

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

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

30. Bishop's method of stability analysis

is more conservative

neglects the effect of forces acting on the sides of the slices

all of these

assumes the slip surface as an arc of a circle
