摘要

The damping coefficient and dynamical load characteristics are sensitive to the dynamic response of the underground powerhouse. In this paper, based on results of dynamic identification of the underground powerhouse of a pumpedstorage power plant previously made, the immune algorithm is used together with the ANSYS Code and the highfrequency water pressure pulsation during a routine operation and the damping ratio are identified and studied with observed data. This will be useful for generating a precise numerical model and studying the hydropower station.
