| 摘 要： | 有些重要工程或场地条件很差的工程，依据常规的方法难以确定其场址的设计地震动参数，常常需要依据或参考场址动力分析结果做出决策，本文着重讨论了输入运动的确定和根据场址动力反应分析结果如何选取设计地震动参数的方法，并以实例加以说明。

| Abstract: | The design parameters of ground motions for some important projects or some sites with very poor conditions, are difficult to be determinated using the conventional method. Thus decision making is frequently required according to the results obtained from the dynamic analysis of these sites. In this paper, rational procedures for deciding input motions of the analysis and evaluating these analytic results have been presented because they are very critical for determinating reasonable design parameters of ground motions. |
