The dynamic response perturbation of structures due to elastic waves is typically associated with energy. Using MATLAB's powerful numerical simulation capabilities, we calculated the energy flux density for SH waves incident on a circular cavity and normalized the results. The findings indicate that the incident frequency significantly impacts the energy flux density. High-frequency waves, despite their rapid local variations, experience rapid energy attenuation, resulting in a more dispersed overall energy flux density distribution. In contrast, low-frequency waves exhibit a relatively smooth energy flux density distribution. These research outcomes are crucial for enhancing the safety and stability of underground structures.
