FINAL EXAM

Question 1

The slip failure is continuous from the edge of the footing to the soil surface and full shear resistance of the soil is developed along the failure surface.

Answer 1

General Shear Failure

Question 1

The failure surface extends from the edge of the footing approximately the boundary of the Rankine Passive State.

Answer 1

Local Shear Failure

Question 2

It is assumed to remain intact during failure.

Answer 2

Zone 1

Question 3

It undergoes considerable plastic flow.

Answer 3

Zone 2

Question 4

It represents the passive state.

Answer 4

Zone 3

Question 5

One of its applications is to provide uplift resistance and or lateral load capacity.

Answer 5

Deep Foundation

Question 6

These are piles which are driven into the ground and include both low displacement and high displacement piles.

Answer 6

Driven Piles

Question 7

These foundations include both drilled piles and piers and foundations constructed in open or braced excavations.

Answer 7

Excavated Foundation

Question 8

It was developed to deliver a standard amount of mechanical energy (compactive effort) to determine the maximum dry unit weight of a soil.

Answer 8

Proctor Compaction Test

Question 9

It consists of a glass or plastic jar with a funnel attached to the neck of the jar.

Answer 9

Sand Cone

Question 10

It is a versatile device to rapidly obtain the unit weight and water content of the soil nondestructively.

Answer 10

Nuclear Density Meter

Question 11

Lines wherein the points are having the same potential energy.

Answer 11

Equipotential Line

Question 12

He proposed that the average flow velocity through soils is proportional to the gradient of the total head.

Answer 12

Darcy

Question 13

It is used to determine the hydraulic conductivity of coarse-grained soil.

Answer 13

Constant Head Test

Question 14

It is used for fine-grained soils because the flow of water through these soils is too slow to get reasonable measurement.

Answer 14

Falling Head Test

Question 15

Steps in the design procedures for bored piles.

Answer 15

1. Evaluate the subsurface condition.
2. Review foundation requirements including design load and allowable settlement.
3. Evaluate the anticipated construction conditions and procedures.
4. Incorporate local experiences and practices.
5. Select appropriate foundation types based on the above items and cost.
6. Determine the allowable design load based on the evaluation of ultimate foundation capacity.
