摘　　要：从加速度反应谱出发,结合国内外人造地震波的主要合成方法,通过软件的拟合对比分析,研究讨论了一些参数对拟合结果的影响,并生成了与我国建筑抗震规范的标准反应谱拟合结果较好的人工地震波。还将其应用于苏州多处隧道与管廊实际工程的弹性动力时程分析中。根据实例分析结果表明:拟合的人工地震波用于时程分析,所得到的响应结果与反应谱法以及天然波分析得到的响应结果偏差较小,满足我国相应规范对时程分析的要求。From the acceleration response spectrum,combined with the main synthetic methods of artificial seismic wave at home and abroad,by fitting,comparison and analysis of the software,the influences of some parameters on the fitting results are studied and discussed,and the artificial seismic waves are generated which fit well with the standard response spectrum of Chinese building seismic codes,and also used in the elastic dynamic time-historical analysis of many actual tunnel and utility tunnel projects in Suzhou.The analysis results of the examples show that the fitted artificial seismic wave is used for the time-historical analysis.The response results obtained have little deviation from those obtained by the reaction spectrum method and the natural wave analysis,which meet the requirements of the corresponding specifications on the time-historical analysis in China.
