【摘要】 本文分析了现行“建筑抗震设计规范”（ＧＢＪ１１—８９）中的场地分类方法并指出其中的不足。根据对大量的实际场地的理论计算，发现场地传递函数的幅值谱有一定的规律性，以此为根据提出了一种新的场地分类方法，为场地分类方法的研究提供一个新的思路。更多还原

【Abstract】 This paper analyses the method of site classification in current "Seismic design code for buildings" (GBJ11 - 89), and points out some deficiencies of this method. Based on theoretical computation results of a great number of sites, we find some laws of amplitude spectrum of transfer function, put forward a new method of site classification and present a new idea for studying the method of site classification.更多还原
