Analysis of the ground vibration induced by high dam flood discharge using the cross wavelet transform method
As flood is discharged in the high dam, vibrations are generated and transmitted to the surrounding ground, causing vibrations in adjacent structures. The vibration can sometimes reach such a high level that can be harmful to the neighboring residents and buildings, which is an undesirable phenomenon and should be prevented. In this study, an attempt has been made to identify the vibration sources, analyze the law of vibration propagation, and establish the relationship between the vibration sources and ground vibration using the Time-Wavelet Power Spectrum and the Cross Wavelet Transform techniques. The results reveal that the flow fluctuating loads generated by different discharge structures are the main cause of the ground vibration. The contribution from each vibration source as well as its attenuation during propagation is different, based on the ways of flood discharge and composition of the grounds. The results lay a good foundation for controlling the ground vibration induced by flood discharge of high dams in the future.
