Here are Foundation Engineering MCQs (Chapterwise).
1. How can foundations be broadly classified?
a) Pile foundation
b) Shallow foundation and Deep foundation
c) None of the mentioned
d) All of the mentioned
View Answer
Explanation: Foundations may be broadly classified under two heads: shallow foundations and deep foundations.
2. Which of the below is the most commonly used shallow foundation?
a) Combined footing
b) Raft footing
c) Strap footing
d) Spread footing
View Answer
Explanation: In spread footing, load is transmitted through an isolated column or wall to the subsoil; hence this is most common type of foundation.
3. When do strap footings are used in foundation?
a) Distance between the columns are long
b) Two column loads are unequal
c) To transfer load of an isolated column
d) All of the mentioned
View Answer
Explanation: A strap footing may be used where the distance between the columns is so great that the combined trapezoidal footing becomes quite narrow, with a high bending moment.
4. According to IS codes, what is the maximum differential settlement that should not be exceeded in the foundation on clayey soil?
a) 28 mm
b) 25 mm
c) 100 mm
d) 45 mm
View Answer
Explanation: According to IS: 2950-1965 code of practice, the maximum settlement should not exceed 40 mm in the foundation on clayey soils and 25 mm in foundations on clayey soils.
5. The conventional method for designing raft foundation is based on which of the following assumptions?
a) Foundation is infinitely rigid and Soil pressure is assumed to be planar
b) Overburden pressure is assumed as zero
c) None of the mentioned
d) All of the mentioned
View Answer
Explanation: The conventional method is based on the following two basic assumptions:
i) The foundation is infinitely rigid and therefore, the actual deflection of the raft does not influence the pressure distribution below the shaft.
ii) The soil pressure is assumed to be planar such that the centroid of the soil pressure coincides with the line of action of the resultant force of all the loads acting on the foundation.
6. What is the purpose of using a bore guide in an under-reamed pile foundation?
a) To provide a support to the pile
b) To drill the bore hole
c) To set the guide assembly in position
d) To keep the bore holes vertical
View Answer
Explanation: The used of boring guide is essential in order to keep the bore holes vertical and also in its position.
7. What forms the most common type of deep foundation for bridges?
a) Pier foundation
b) Shallow foundation
c) Well foundation
d) Pile foundation
View Answer
Explanation: In India, well foundation forms the most common type of deep foundation for bridges.
8. What is a disadvantage of using a circular shape for a well foundation?
a) Diameter of well is more than required
b) Sinking is more uniform
c) Minimum perimeter
d) Skin friction is maximum
View Answer
Explanation: The disadvantage of a circular well is that in the direction parallel to the span of the bridge, the diameter of the well is much more than the minimum size required.
9. What are the horizontal forces that are prone to act on a well foundation?
a) Seismic force
b) Wind force
c) Earth pressure
d) All of the mentioned
View Answer
Explanation: A well foundation is liable to the following horizontal forces: i) force on account of water current ii) wind forces iii) seismic forces iv) earth pressure v) centrifugal forces.
10. What is the rotation of the foundation about the y-axis known as?
a) Pitching
b) Rocking
c) Yawning
d) All of the mentioned
View Answer
Explanation: In the general case, rotation about y, z and x-axes are respectively known as rocking, yawning and pitching.
11. Which of the following pavement is capable of resisting small tensile strength?
a) Flexible pavement
b) Rigid pavement
c) Semi-flexible pavement
d) All of the mentioned
View Answer
Explanation: A flexible pavement consists of relatively then wearing surface and hence, can resist only very small tensile strength then the other pavement.
12. What level of tensile stresses do flexible pavements resist?
a) very large
b) negligible
c) large
d) only very small
View Answer
Explanation: The flexible pavements consists of thin wearing surface which is built over a base and sub-base course and are able to resist only small tensile stresses. The semi flexible pavement can possess appreciable flexural strength.
13. If there is no friction between the slab and the sub-grade, what occurs in the slab?
a) temperature gradients
b) no stresses
c) small number of stresses
d) large number of stresses
View Answer
Explanation: The stresses are set up in the slab due to uniform temperature changes. If this is absent and the slab is free to move without resistance, then there is no friction between the slab and sub-grade. Thus, if there is no friction between the slab and the sub-grade, then there are no stresses in slab.
14. The foundation that is used when the soil mass is sufficiently erratic?
a) Mat footing
b) Rectangular combined footing
c) Strap footing
d) Combined footing
View Answer
Explanation: Mat footing is used where the soil contains compressible lenses or the soil is sufficiently erratic so that the differential settlement would be difficult to control.
15. How is the settlement of the plate in a load test measured?
a) Datum bar
b) Measuring unit
c) Test plate
d) Sensitive dial gauges
View Answer
Explanation: The settlement of the plate is measured with the help of sensitive dial gauges. For square plate, two dial gauges are used. The dial gauges are mounted on independently supported datum bar.
