TO GEOTECHNICAL ENGINEERING
By the end of
today's class, you should be able to do the following:
Make a list of the types of projects on which engineering geologists
and geotechnical engineers work.
appropriately to the list of skills in
should you bring to this
* List the eight
common rock-forming minerals mentioned in your textbook and describe
their properties and general
(feldspars, quartz, ferromagnesian minerals, iron oxides, calcite,
dolomite, mica, and gypsum)
* Describe hand
samples of the common rock-forming minerals; give mineral names where
* Suggest why
some of the specific properties of these minerals might be of
importance to a geotechnical engineer.
* Name and give
concise definitions of the three major classes of rocks. For each
one, list subgroups and describe their formation and important
* Examining hand
samples of various types of rocks, construct reasonable hypotheses as
to how they formed; classify them according to your hypotheses.
* Suggest why
some of the specific properties of these rocks might be of importance
to a geotechnical engineer.
* Describe the importance of discontinuities (bedding
planes, schistocity, folds, joints,
and fractures in engineering analysis).
the different goals and purposes of geologists and geotechnical
engineers, write definitions of "soil", "sediment", and "rock" that
would be suitable for each group.
* Describe the characteristics of six different environments of soil
formation mentioned in the textbook.
(residual, glacial, alluvial, lacustrine, aeolian,
and colluvial soils)
* Answer "Questions and Practice Problems", p. 32-33: Problems
2.1, 2.2, 2.3, 2.4, 2.5, and
Questions and Practice Problems", p. 45: Problems
2.13 through 2.19.
