| 摘 要： | 本文针对辽河特大桥项目进行了空间相关多点地震动合成的研究。在单点地震动合成的基础上，引入相干函数反应空间各点的相干性，用视波速反应行波效应，并通过matlab来实现。对4个输入点，进行了地震动合成。合成地震动反应谱与目标反应谱误差在5％以内。

| Abstract: | Based on the previous researchers＇ results, this paper simulates the spatial correlative time histories of multi-point ground motion for the oversize Liao bridge using the Matlab program. We introduce the coherence function to reflect the coherence of the points in the spatial field, and use the apparent velocity to reflect the wave passage effect. For 4 inputed points, simulate the time histories of ground motion acceleration, and the bias of the calculated spectra and the objective spectra is no more than 5%. |
