“…While much of the very detailed information contained in the description plays only a minor role in engineering design, there may be occasions when it is required. A representation scheme which can handle the majority of soil descriptions was put forward by Toll et al (1991), and this scheme has been extended during the implementation of the database.…”

“…It has been developed as part of a knowledge-based (expert) system (called SIGMA) for the interpretation of geotechnical information (Toll et al 1992;Toll 1994). The role of the knowledgebased system (KBS) is to assist the geotechnical specialist with both the interpretation of ground conditions across a site and the assessment of design parameters from numerical information (laboratory and field test results).…”

The paper describes the development of a database for geotechnical information. The database is part of a knowledge-based (expert) system for the interpretation of geotechnical information. It has been implemented using the INGRES relational database management system. A particular feature, unique to the database structure developed, is the ability to store layer descriptions in a structured form. In other database systems these are simply stored as single text fields. A complex structure has been derived which can accommodate the full range of layer descriptions: for example, interbedded soils/rocks within a layer, the variation in description from top to bottom of a layer, and the existence of multiple soil or rock types within a description. The paper presents details of the database tables with examples of how the structured representation is used.
