Accessing Geoenvironmental Data: From On-line to Expert Systems
Examination of the values of the initial volume Vo and the limit pressure can show
us a deviation. A production rule called Demon is written for such a task.

CONCLUSION
This expert system project is a response to a current need in the geotechnical
engineering domain and follows a tendency in research to reinforce the quality
assessment process in information systems. The GDQ-EXPERT system described
above provides a tool for design engineers to assess the quality of test data and
existing geotechnical databases.
KEYWORDS
Expert system, geotechnical data, quality assessment, property of soils, soil erosion,
object oriented language, geotechnics, geomechanics.
