For the first time, the wave pattern similarity had been combined with dynamic response behavior of the underground pipeline structure for study, it had been proven that a significant effect does existSbetween the two aspects, the internal force response values and the coupling wave pattern similarity. On the other hand, a further research had been made to get a rule that the internal stress changing with the coupled wave similarity.SSIn the generation of similarity wave, an advanced method had been adopted in this paper, wavelet decomposition and reconstruction. This method not only make the waves similarity and the initial components of every wave can be adjust, but also make the time of appearing of every frequency can be adjusted. So, it made the generation of every similarity wave at any local site conditions is possible. At the same time, it also make the ground motion input become possible in any conditions.
