Representing geotechnical properties in a knowledge-based system
A knowledge-based system for the estimation of geotechnical design parameters is described, The form of representation and the way in which this has been implemented using an object-oriented knowledge-based system development environment (ProKappa) are explained. Three knowledge bases for ground types, ground parameters and 'typical' values have been established as object hierarchies. The knowledge bases hold ranges of typical values for geotechnical parameters for a wide variety of ground types. Different qualitative properties of the ground are also represented. A user interface allows identification of the soil or rock type for which properties are to be estimated and this is matched at the appropriate level of detail within the knowledge bases. Estimation can be done both in terms of the ground type and qualitative properties such as plasticity, consistency, mineralogy, particle shape, etc. The knowledge representation scheme adopted allows combinations of qualitative properties to be considered. A knowledge acquisition facility has also been provided to allow users to add their own knowledge to the system. Users can add new parameters, extend the number of qualitative properties considered and even establish new ground types.
