TO GEOTECHNICAL ENGINEERING
By the end of
today's class, you should be able to do the following:
* Report, compare, and analyze the results of the soil moisture
* 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)
* Using the mass of
your dry soil sample, estimate the volume of solids in your soil sample.
* Using the density of water, estimate the volume of water that was in
your moist soil sample, before you dried it.
* Calculate the degree of saturation of your moist soil sample.
* Solve weight-volume
problems that ask you to use the values of some
soil properties to calculate the values of others.
