EOSC 210 Final Test Questions
with Correct Answers
what are some types of concrete dams - Answer- gravity, arch, buttress, concrete-face
(hybrid)
what are some pros to concrete dams - Answer- rigid
offer more resistance to water erosion, overtopping and piping failure
can be shaped to support imposed loads, reduce tensile stresses and minimize
concrete usage (thin arch dams)
what are some cons to concrete dams - Answer- concrete is relatively expensive
somewhat more labor intensive than earth dams
concrete has low tensile strength making it susceptible to differential settlements
requires appropriate sources of sand and gravel aggregate for concrete
gravity dams - Answer- use bulk weight and low center of gravity to hold back water.
can be built across long distances over relatively flat terrain (most applicable in non-
mountainous regions)
entire load concentrated on foundation
buttress dams - Answer- use multiple reinforced columns to support a dam that has a
relatively thin structure
uses 1/2 as much concrete
limited height
can be considered even if the foundation materials are a bit weaker
buttress - Answer- a support that transmits a force from a roof or wall to another
supporting structure
arch dams - Answer- utilize the strength of an arch to displace the load of water behind
it on its abutments
use less material than gravity dams but are a lot more expensive
only built when walls of a canyon are unquestionalbly stable and impervious to seepage
around the dams as this could cause failure
where are arch dams usually located - Answer- narrow, deep river gorges
what are the requirements for a dam foundation - Answer- adequate strength and low
compressibility
