Document Type: Proceeding Paper

Abstract: An expert system is presented that will assist a field inspector, during the site investigation of an existing concrete dam, to perform a preliminary structural risk assessment of the dam. The expert system models the qualitative engineering reasoning required for a deterministic risk assessment. Conceptually, the preliminary risk assessment of a concrete dam is a problem of identification and classification of symptoms. The classification of the symptoms leads to the diagnosis of the failure modes and the recommendation of possible remedial measures. The knowledge is structured in an inference tree of nearly-decomposable problems. Frames and rules are used for the knowledge representation.
