中文摘要：
克服了传统非一致性激励输入中仅能考虑时间差动的缺点,采用小波分解与重构手段来构建一系列空间相似性耦合波型,该方法具有频率成份的含量及其出现的先后顺序可以调整的特点,因此可以模拟天然地震动中的局部场地条件突变,使一种能够满足多方面条件的非一致性输入成为可能。另外,将耦合波型的相似性与地下管道结构的动力响应相结合,通过大型振动台实验,研究了地震作用下管道结构内力随耦合波型相似性变化而变化的规律。结果表明管道结构两相邻质点间耦合波型的相似性对管道内力响应值存在着显著影响,并得到了一系列非一致性激励试验中较为重要的规律。
英文摘要：
The defect had been overcome in this paper that there was only the differential time can been considered in the traditional inconsistent excitation input.The wavelet decomposition and reconstruction method was used to build a series of spatial similarity coupling waves in this paper,which can simulate the mutation of local site conditions in the natural ground motion,just because of the characteristics that the harmonic content and the order can be adjusted.So it made a way to meet all kinds of various site conditions about inconsistency input.On the other hand,the wave coupling similarity was been combined with the dynamic response of the underground pipeline structure for the first time,then a series of rule been obtained when the internal force of pipeline structure changing with the similarity of coupled waves,through this large scale shaking table test.The results show that it had a significant influence on the internal force response values,the coupling wave similarity between the two adjacent particles in the pipeline structure.Finally,a series of important rule had been obtained in this inconsistency motivation test.
