Spring, 2007

Daily Objectives #4  (January 18, 2007)                                                                                  Dr. Sanders

By the end of today's class, you should be able to do the following:

From last week...

* Respond appropriately to the list of skills in
What should you bring to this course?



Discontinuities


* Describe the importance of discontinuities (bedding planes, schistocity, folds, joints, and fractures) in engineering analysis.



Sediments and Soil

* Considering 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 on pages 33-43.

    (residual, glacial, alluvial, lacustrine, aeolian, and colluvial soils)

* Explain why understanding the engineering properties of soil and rock is useful in common projects such as building of, say, a parking garage.


Testing Your Knowledge

* Answer "Questions and Practice Problems", p. 32-33:  Problems 2.1, 2.2, 2.3, 2.4,
and 2.5.
 

* Answer "Comprehensive Questions and Practice Problems", p. 45:  Problems 2.13 through 2.19.  In answering the problem assigned to you, discuss it first with a partner, then present to your colleagues the following information:
            --Location of the study site
            --Sketch of a geologic cross section, plan view map, or other representation of the important geological aspects of the situation.
            --A brief summary of the question/problem posed
            --Your response
            --Any further geologic considerations that might be important.
