摘　　要：在抗震设计中,场地是指具有相似的反应谱特征的工程群体所在地,不仅仅是房屋基础下的一小块地基土。其范围相当于厂区、居民小区和自然村或不小于1.0 km 2的平面面积。结合场地的概念,通过对一些项目地基处理前后场地类别的分析,从地基处理对场地类别及特征周期的影响,提出了通过地基处理实现上部结构减震的方法。In seismic design,a site refers to the location of an engineering group with similar response spectrum characteristics,not just a small piece of foundation soil under the foundation of a house.It’s scope is equivalent to or not less than a factory,residential district and natural village.A plane area of 1.0 km 2.Based on the concept of site,this paper analyzes the site types before and after foundation treatment for some projects.From the impact of foundation treatment on site types and characteristic period,a method is proposed to reduce the seismic action of superstructure by foundation treatment.
