"AN INTRODUCTION TO DRILLING & SAMPLING IN GEOTECHNICAL PRACTICE."

  • by Jason T. DeJong & Ross W. Boulanger, 2nd Edition (2000)

GENERAL DESCRIPTION OF THE VIDEO

  • This 35-minute video presents an overview of typical drilling and sampling methods in Geotechnical Engineering practice. Topics include types of drill rigs, rotary wash drilling, solid and hollow stem auguring, SPT testing, thin-walled tube sampling, Pitcher barrel sampling, rock coring, and sample disturbance.
  • This amateur video was produced as an undergraduate independent study project (ECI-199) at UC Davis in 1996. A revision was completed in 2000 based on feedback from friends and colleagues who have used it in their undergraduate and graduate courses. The revisions are significant enough (including a new voice!) to warrant replacing older copies.
  • We require students to view the video as part of an assignment. This allows students to view the video more closely and review portions as they wish. We have found this approach to be more effective than showing it in the classroom.
  • Support was provided by the National Science Foundation through Career Award CMS-95-02530 and by the Teaching Resources Center & Instructional Media Services of the University of California, Davis. Taber Consultants performed the drilling shown in the video. The above support, and assistance of many other people, are all greatly appreciated.

DIVX & XVID VERSIONS

  • The DVD version was compressed for web delivery in 2006 (thanks to Robert Jaeger for volunteering his time). For any of these files, right click and choose "save target as" in order to download the file (as opposed to trying to run it directly).
  • One set of compressed files uses the DivXPLay codec (open in this window or a new window, which you must download and install on your computer first. Then you can play either of the following versions:
    • 665 MB version (best available quality)
    • 150 MB version (lower resolution, but not too bad)
  • Another set of compressed files use the XviD codec (open in this window or a new window, which you must similarly download and install on your computer first. Then you can play either of the following versions:
    • 665 MB version (best available quality)
    • 150 MB version (lower resolution, but not too bad)

MPEG & QUICKTIME MOVIE VERSIONS

  • The video is also available as MPEG and Quicktime movies, but their resolution is generally not as good as the compressed DivX or XviD files at comparable file sizes.
  • The MPEG version is 350-Megabytes and is available at http://cee.engr.ucdavis.edu/faculty/boulanger/video/DrillingAndSampling.mpg .
  • The Quicktime files include the entire video in one file, plus the video broken down into five files covering the different sections of the movie.

STILL IMAGES

  • A large set of "still" images from the movie files is contained in this zip file. They are of limited resolution, but can be useful for classroom powerpoint presentations.

DROP US A NOTE

  • Jason and I would appreciate a brief email letting us know if you download the video and find it useful in your teaching and/or learning about geotechnical engineering. After all, our motivation in sharing the video is to see it get used. Thanks.
