TO GEOTECHNICAL ENGINEERING
By the end of
today's class, you should be able to do the following:
* List the three phases of soils.
* Explain the difference between volume, mass, and weight of the three
phases of soils.
* Explain what
the following quantities reveal about a soil, and using
a soil phase diagram, define each one:
q porosity (n)
q degree of
q unit weight (g):
unit weight of the soil sample
unit weight of water
dry unit weight
s density of the soil sample
s density of water
q specific gravity of solids (Gs)
q void ratio (e)
q relative density (Dr)
* Explain how to
in the laboratory. You should have brought in a soil sample for
today. By Thursday, determine its moisture content
using our laboratory equipment.
* Solve weight-volume
problems that ask you to use the values of some
soil properties to calculate the values of others.
