摘要


本文从地震动合成出发,在考虑场地条件、震源参数等影响的情况下,采用随机有限断层法合成了场地基岩场地相隔一定距离处空间各点的加速度时程,进而研究这些点之间的相干性。本文的研究结果验证了基岩场地相干函数计算模型的合理性;同时说明,随机有限断层法得到的地震动加速度时程能够体现地震动的内在特点,可以将其作为高耸结构、大垮桥梁等重要工程结构抗震分析时的多点地震动输入。





Abstract

In considering of the site conditions and source parameters, this article starts from synthesis of the earthquake ground motion, and synthesizes the accelerograms on bedrock at some specified points by stochastic finite faults method, then researches the strong ground motion coherence among these points. It proves that the coherency model on bedrock is of rationality through comparing the synthesis results. Meanwhile, it is known that the accelerograms simulated by stochastic finite fault method can be used as the multi-point input for high-rise structures, long-span bridge and other key engineering structural aseismic analysis.
