摘要

Large dams are exposed to environmental loads during their service life. The associated structural damage can jeopardise stability and must be detected early on by monitoring measures. This article examines the conditions under which the characteristic vibration behaviour can change as a result of stiffness reductions due to structural damage in order to detect and localise these areas. Using the Enguri dam as an example, the effects of different damage scenarios on the vibration behaviour are investigated numerically and a sensor layout is designed for a measurement-based vibration analysis.
