"An Introduction to Drilling & Sampling in Geotechnical Practice"
Revised July 2000
Jason T. DeJong (jdejong@ucdavis.edu) & Ross W. Boulanger (rwboulanger@ucdavis.edu)
General Description of 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 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.
Support was provided by the National Science Foundation through Career Award CMS-95-02530 (PI: Ross Boulanger) and by the Teaching Resources Center 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, which you must download and install on your computer first. Then you can play either of the following versions:
- Another set of compressed files use the XviD codec, which you must similarly download and install on your computer first. Then you can play either of the following versions:
JPEG Still Images
Digitization of the video has enabled still images (JPEG format -- 320x240) to be captured from the video for use in printed and multi-media (e.g. Powerpoint) documents. Images from each of subsection have been condensed into zipped folders as follows.
