摘    要:随着现代强震仪及通讯技术的发展, 强震动观测资料的应用范围愈来愈广, 强震观测可以拓展到地震观测领域, 强震数据的实时仿真是这一拓展的基础. 为适应这一发展趋势, 在笔者曾经提出的单自由度系统地震反应递归公式的基础上, 本文提出了一套基于地震仪原理, 及长周期单自由度系统地震动力反应原理的由宽频带强震动记录仿真位移记录的新方法. 研究表明此方法是有效的, 可广泛应用于地震监测. 

关 键 词:强震动记录    单自由度系统    位移    仿真

Abstract:With the development of accelerograph, strong ground motion data can be widely applied to many fields. Especially, it is an important milestone for strong motion observation to expand application fields into earthquake monitoring that real time simulation of ground displacement can be obtained by strong motion records for determining three earthquake parameters. For the purpose of application, on the basis of principle of seismic response of single degree of freedom (SDOF) system, this paper presents a suit of formula of simulating ground displacement records by using strong ground motion records with the help of simulator of SDOF system. The research results show that the technique is very efficient and can be widely applied to earthquake monitoring.
Keywords:strong motion record  SDOF system  displacement  simulation
