Objectives of the study
Arch dams have been widely constructed around the world due to the advantages of economy, safety and reliability. The strong uncertainty of earthquakes makes it possible for arch dams to be subjected to over-designed earthquakes, which may lead to extremely serious casualties and property losses. In actual concrete arch dam engineering scenarios, the dynamic data obtained by the health monitoring system of an arch dam are incomplete. The data acquired typically depend on the state of the dam structure, that is, whether it is intact or incomplete. Accordingly, the formulation of an accurate, efficient, and intelligent damage warning and identification model for concrete arch dams is necessary to ensure infrastructure safety.
