Geotechnical Engineering - Final Exam
Questions and Answers Verified
Solutions .
Soil Mechanics - CORRECT ANSWERS Study of physical properties of soil and it's behavior
under applied forces. It also deals with flow of water through soil and it's a combination of solid
mechanics and fluid mechanics.
Igneous Rocks - CORRECT ANSWERS Formed from magma cooling
Sedimentary Rocks - CORRECT ANSWERS formed by the deposition of material at the
Earth's surface and within bodies of water. ( Soil layers being compressed by pressure "lithification")
Metamorphic Rocks - CORRECT ANSWERS formed from pressure and head, this process is
also known as metamorphism.
Organic Soils - CORRECT ANSWERS formed from decayed plant and animal life
Inorganic Soils - CORRECT ANSWERS chemical and mechanical weathering of rocks
Weathering - CORRECT ANSWERS process of breaking down rocks by mechanical and
chemical process.
Mechanical Weathering - CORRECT ANSWERS rocks are broken down without any change
in the chemical nature of the rocks. (temperature change)
Chemical Weathering - CORRECT ANSWERS rocks are broken down by chemical reactions.
(carbonation, oxidation, hydration)
, Sieve Analysis - CORRECT ANSWERS consists of shaking soil sample through set of sieves
that have progressively smaller opening.
What is the opening in (mm) for sieve number 4? - CORRECT ANSWERS 4.75 mm
What is the opening in (mm) for sieve number 200? - CORRECT ANSWERS 0.075 mm
At what particle diameter size is Hydrometer Analysis used for? - CORRECT ANSWERS used
for particle size less than 0.075 mm in diameter (or opening)
Stroke's Law - CORRECT ANSWERS Rate of settlement of solid spheres dispersed in a
liquid.
Effective Size (D10) - CORRECT ANSWERS diameter from curve corresponding to 10% finer
The unit weight of water is equal to ( English units) - CORRECT ANSWERS 62.4 lb/ft^3
The unit weight of water is equal to (SI Units) - CORRECT ANSWERS 9.81 kN/m^3
Volume is a function of - CORRECT ANSWERS Temperature and Pressure
What does it mean when soil sample is saturated? - CORRECT ANSWERS The void spaces
are completely filled with water.
Shrinkage Limit - CORRECT ANSWERS Moisture content at which the transition from solid
to semisolid state takes place.
