EOSC 210 exam Questions with
Detailed Verified Answers
Question: what is site investigation and what is it used for
Ans: drilling under ground to find what material is underneath
used to decide where to build
Question: structural eng vs geotechnical eng
Ans: structural : deductive : starts with well known conditions
geotechnical : inductive : limited knowledge that must be gained through
stats and judgement
Question: parameter uncertainty
Ans: spacial variations in material properties and lack of data for
parameters
Question: what is human uncertainty subject to
Ans: measurement error and opinions
Question: when is the yield stress high on the graph
, Page | 2
Ans: when material is brittle
Question: rock quality designation equation
Ans: RQD = sum(length of core pieces)/(total length of the core) *100
Question: where do earthquakes usually happen and why
Ans: at Marins of tectonic plates because of friction
Question: what is the ring of fire
Ans: subduction zones where lots of EQ happen
Question: what kind of failure is EQ
Ans: brittle
Question: what is the focus/hypo center
Ans: where energy is released in an EQ
Question: epicenter
Ans: point on surface above focus/hypo centre
Question: how do body waves transmit energy and what two kinds are there
, Page | 3
Ans: transmit energy in interior (S and P)
Question: how do surface waves transmit energy and what two kinds are
there
Ans: transmit on surface and (love and Rayleigh)
Question: primary/compression waves (P) and what it moves through
Ans: like a spring
solids and liquids
Question: secondary/shear waves (S) and what it moves through
Ans: waves
solids (so not in core of earth! )
Question: love waves (L) and what it moves through
Ans: surface shaking <2km solid only
Question: Rayleigh waves (R) and what it moves through
Ans: surface rolling (drop in water) damages rigid buildings through solids
and liquids
Question: seismometers/sensors where are they put
