利用６５次地震的中国数字地震台网（ＣＤＳＮ和ＮＣＤＳＮ）宽频带和甚宽频带（ＢＢ及ＶＢＢ）记录，分别计算了阻尼比ζ＝０．００５，０．０１，０．０２，０．０５和０．１０的基岩水平向相对位移反应谱、相对速度反应谱和绝对加速度反应谱．结果表明，工程上常用的强震加速度记录，不足以给出可靠的长周期地震动反应谱，而ＣＤＳＮ宽频带记录恰恰可以作为强震加速度记录的重要资料补充来源，用于长周期地震动反应谱特性的研究． Using the broadband and very broadband (BB and VBB) records of China Earthquake Network (CDSN and NCDSN) of 65 earthquakes, the damping ratios ζ = 0.005, 0.01, 0.02 and 0.05 And 0.10 bedrock horizontal relative displacement response spectrum, relative velocity response spectrum and absolute acceleration response spectrum. The results show that the strong earthquake acceleration records commonly used in engineering are not enough to give reliable long-period ground motion response spectra. However, the wide-band CDSN record can be used as an important source of seismic acceleration records to supplement the long-period ground motion response Study of spectral characteristics.
