Abstract

The natural frequencies of the Chirkey arch dam extracted from the microseismic noise by coherent reconstruction of standing-wave fields are analyzed. It is for the first time that the natural frequencies of a dam were determined and its modes of vibration were detailed after a natural experiment. The results can be used as input data for monitoring the dam conditions.
