At present, the methods of site classification were difficult to be achieved in some wide field. Therefore, it is necessary to study new methods of site classification. In this paper, based on the geologic features, a new method is suggested by applying the Geological Information System technology. Combined with the geological survey data and the description of NEHRP, the soil classification matrix is given which could be used as lookup table in GIS and the soil class map is compiled. Then the effectiveness of this site classification method was verified by the borehole data.%我国现有的场地分类方法,难以实现大范围区域性的场地分类,因此,有必要探索新的场地分类方法,用于实现区域性场地分类.本文在搜集地质资料的基础上,结合NEHRP的场地分类描述,通过建立地质特征与场地分类的关系表,形成了一种新的区域性场地分类方法,并以实际钻孔资料获得的场地分类验证了这种分类方法的有效性.
