Abstract
A knowledge-based system has been developed to provide assistance in the selection of appropriate geotechnical in-situ tests. It has been implemented using PDC Prolog on a Personal Computer. The system makes use of two knowledge bases: A Ground Knowledge Base containing knowledge concerning the ground (at the level of detail required by the system) and a Tests Knowledge Base containing information about the tests themselves. The identification, collection and representation of the domain knowledge is discussed. A hierarchical knowledge representation scheme has been developed which can represent both the ground and the test information. In order to access this knowledge, an extended inference mechanism (over that provided by PDC Prolog) has been implemented. This consists of domain independent rules which provide inheritance and transitivity inferences as well as information retrieval.
