  1. Skempton’s equations give the ............ bearing capacity of ............ footings founded in
    purely cohesive soils.

  2. Skempton’s equations do not suffer from the limitation that the footings must be shal-
    low (Df/b ≤ 1). True/False.

  3. Brinch Hansen’s theory of bearing capacity gives better results for cohesive soils rather
    than for cohesionless soils when compared with Terzaghi’s theory. True/False

  4. Net ultimate bearing capacity of a footing in purely cohesive soil is reduced by about
    50% if the water table rises to the ground surface. True/False.

  5. Abbet’s improved method of plotting is used for plotting the results of a ............ test.

  6. Size effects in plate load tests are more important in the case of ............ soils.

  7. Standard penetration Test is commonly used for cohesionless soils. True/False

  8. Standard penetration test results for a cohesionless soil are correlated to its ............ and
    .............

  9. In the case of cohesionless soils, invariably the ............ criterion for the allowable bear-
    ing pressure governs the design.

  10. Pile foundation is one of the type of ............ foundation.

  11. When the weight of the soil excavated to place the foundation equals the total weight of
    the structure the foundation is said to be a ............ foundation.

  12. When the area of all the footings covers more than fifty percent of the area of the struc-
    ture, a ............ foundation is considered more suitable.

  13. For ordinary buildings, dead load plus half of the live load is referred to as the ............
    load for the column.

  14. Useful width concept is an approach for the determination of the bearing capacity of
    footings subjected to .............

  15. When the footing of an exterior column cannot be allowed to extend beyond the adjacent
    property line, either a ............ footing or a ............ footing may be used.

  16. When the allowable soil pressure is low and the expected differential settlement for
    spread footings is high, the best choice is ............ foundation.

  17. The coefficient of subgrade reaction of a soil is defined as .............

  18. The modulus of elasticity of a cohesionless soil ............ with depth.

  19. The modulus of elasticity of a cohesive soil ............ with depth.

  20. Based on the mode of supporting vertical loads, piles may be classified as ............ piles
    and ............ piles.

  21. Three important materials used for piles are ............, ............, .............

  22. Perhaps the most complete dynamic pile driving formula is ............ formula.

  23. The ratio of the energy after impact to the energy of a pile driving hammer before im-
    pact is known as the ............ of the hammer

  24. One of the simplest of the dynamic pile-driving formulae is the ............ formula.

  25. There is a possible reduction in pile through liquefaction if a pile is driven into .............

  26. Dynamic resistance of soil is not much different from its static resistance. True/False.
