在悬索桥、埋地管道等大型线状或网状结构的动力分析中，不可避免地需要一个输入模型来表示相互关联的地震动特性。在此背景下，本文研究了一种利用自回归模型模拟地震地面运动的方法，该模型在模型表示中考虑了实际传播的地面运动的特性。模拟结果表明，模拟的海浪特性与规定的海浪特性一致，从而验证了该模拟方法的正确性。
An input model properly representing mutually correlated earthquake ground motions is inevitably required in dynamic analysis of large scale line-like or network-like structures such as suspension bridges and buried pipelines. In this context, this paper investigated a simulation method of spatially as well as temporally variative earthquake ground motions by utilizing an autoregressive model where the properties of the actual propagating ground motions were taken into consideration in the model representation. The simulation method was justified by showing the consistency of the properties of simulated waves to the prescribed ones.
