⫸ What are Civil Engineering areas? Answer: Transportation,
Structural, Hydraulic, and Geotechnical
⫸ What does SPT stand for? If you did SPT test and get numbers of 5-
7-6, what is the SPT N for the soil? Answer: Standard Penetration Test;
13
⫸ What are the two design considerations for foundation design?
Answer: Load capacity and settlement
⫸ What is the typical factor of safety for load bearing capacity?
Answer: 3
⫸ What are the three Terzaghi's bearing capacity factors? How do you
determine? Answer: Nc, Nq, Ngamma; with the friction angle using the
chart
, ⫸ The bearing capacity calculated using Terzaghi's method is ultimate
bearing capacity. The allowable bearing capacity can be determined
using the ultimate divided by ( ). The allowable bearing capacity has to
be equal or ( ) than the contact pressure. Answer: factor of safety;greater
⫸ What are the three modification factors in general bearing capacity
formula? Answer: shape, depth, and inclination
⫸ The inclination angle of the load on the foundation is b, which is an
angle with respect to ( ) direction. Answer: Vertical
⫸ What are those three cases for calculating contact pressure? Answer:
centric, one-way eccentricity, and two-way eccentricity
⫸ How to calculate eccentricity if we have moment M and vertical load
Q? Answer: e = M/Q
⫸ What are the three components of settlement? Answer: elastic,
primary and secondary
⫸ What is additional stress? Answer: extra load on the structure from
the soil, settlement is caused by additional stress
⫸ What is Over Consolidation Ratio (OCR)? Answer: OCR = Po/P =
maximum earth pressure/current earth pressure
