1The bearing capacity of soil must be checked because the over-stressing of soil can result in:
- Aexcessive settlement
- Bdamage to the structure
- Cthe shear failure of soil
- Dno transfer of load to the soil
- Enone of the above
2Spread footings and mat footings generally are referred to as [blank_start]shallow foundations[blank_end], whereas pile and drilled-shaft foundations are classified as [blank_start]deep foundations[blank_end].
- Ashallow foundations
- Bdeep foundations
- Cshallow foundations
- Ddeep foundations
3In soil with high load-bearing capacity, it is more economical to construct the entire structure over a concrete pad known as a mat foundation.
- AVerdadeiro
- BFalso
4If the depth of embendment to width ratio is less than four, the foundation is a [blank_start]shallow foundation[blank_end]. If the ratio is greater than four, the foundation is a [blank_start]deep foundation[blank_end].
- Adeep foundation
- Bshallow foundation
- Cdeep foundation
- Dshallow foundation
5For a foundation to function properly the settlement of soil caused by the load must be within a tolerable limit, and shear failure of the soil supporting the foundation must not occur.
- AVerdadeiro
- BFalso
6General shear failure occurs for loose-to-medium dense sand. Local shear failure is for a dense sand layer or stiff soil.
- AVerdadeiro
- BFalso
7Label each bearing capacity failure scenario.
- AGeneral Shear Failure
- BLocal Shear Failure
- CGeneral Shear Failure
- DLocal Shear Failure
8In general shear failure, the soil directly below the foundation (Zone I) is pushed downwards, making the soil very dense and compact.
- AVerdadeiro
- BFalso
9In general shear failure, the soil below the foundation (Zone I) is pushed downward, but the slip surface ends somewhere inside the soil. Therefore, no heave can be seen on the surface.
- AVerdadeiro
- BFalso
10In [blank_start]local shear failure[blank_end], the soil is pushed down and either to the right or left to cause a heaving effect, but never both directions.
- Alocal shear failure
- Bgeneral shear failure
11Terzahi's bearing-capacity analysis considers shallow foundations in the general shear failure condition.
- AVerdadeiro
- BFalso
12What are the bearing capacity factors?
- Acohesion
- Bsurcharge
- Cunit weight of soil
- Ddrain angle of friction
- Enone of the above
13The factor of safety for ultimate soil bearing capacity used to receive the allowable bearing capacity is _____.
- A1.5
- B2
- C3
- D2.5
14Which bearing capacity factor is dependent on the drain angle of friction?
- Asurcharge
- Bunit weight of soil
- Ccohesion
- Dnone of them are affected by a change in the angle
15Terzaghi's bearing-capacity factors will yeild good results for practical purposes, but there are cases where the Meyerhof-Versic equation will provide a significant difference in results.
- AVerdadeiro
- BFalso
16The [blank_start]depth factor[blank_end] accounts for the shearing resistance developed along the failure surface in soil above the base of the footing. The [blank_start]shape factor[blank_end] determines the bearing capacity of a rectangular or circular footing. The [blank_start]inclination factor[blank_end] is used to determine the bearing capacity of a footing on which the direction of the load application is inclined at a certain angle to the vertical.
- Ashape factor
- Bdepth factor
- Cinclination factor
- Dshape factor
- Edepth factor
- Finclination factor
- Gshape factor
- Hdepth factor
- Iinclination factor
