中外场地分类研究现状及其应用讨论

场地类别的不同会影响建筑物的抗震设计，世界各国根据各自的经济水平和抗震理念，有着不同的场地分类标准。本文抓住我国抗震设计规范演变主线回顾了场地类别相关研究进展，重点介绍和对比我国与美国、欧洲和日本等发达国家建筑设计规范中的场地分类的异同，并用工程实例进行分类给出了不同国家场地类别的对应关系，提出了我国场地分类方法可增加计算深度及采用场地周期作为分类指标的建议。

Research progress and application on site classification in the world

Different siteshavedifferent seismic design of buildings.Various countries in the world have different site classification standards according to their economic level and seismic concept.This article reviews the thread Chinese seismic design code evolution site categories related research progress,introducesdifferences of site classification of China,the United States,Europe and Japan.classifying engineering examples of different site classification methods,gives the corresponding relationship between site categories in different countries,is given and pointing out the differences,points out the proposal of increasing the calculation depth and adopting the site period as the classification index in our country.
