摘　　要：工程场地分类是抗震设计的基础性工作。本文总结了传统场地分类方法的基本思路,对目前新兴的基于强震记录的单点水平/竖直谱比场地分类方法做了重点介绍。从基于谱比卓越周期划分场地类别和基于谱比曲线形状划分场地类别两个角度归纳整理了目前这种方法,并且对国内外研究进展及其优缺点做了总结。目前我国强震动台网的部分台站缺少钻孔勘测资料,台站场地分类较为简化,这种方法可以作为一种有效的手段解决这一问题。最后结合我国的实际情况,对该方法实际应用中需要注意的一些问题做了探讨。It is primary for making the structure seismic design to have a reliable local site classification. This paper firstly reviewed and evaluated the traditional methods of site classification. Then a new popular method is introduced which is usually called the horizontaL/vertical spectral ratio method based on the strong motion recordings. Considering the predominant period or spectral ratio shape, different criteria for classifying a site were summarized. At present the borehole profiles are not available for most of strong motion stations in China, this method can be used for site classifications. Some problems in the applications of this method were finally noted considering the current situation of China.
