摘要
强震观测资料和震害资料表明,场地条件对地震动有着重要的影响。从工程抗震的角度出发,依据场地条件对场地进行分类并规定不同场地的设计地震动参数是目前各国抗震设计规范的通行做法,也是当前岩土工程抗震研究的重要内容。本文对国内外抗震规范中场地分类的研究历程进行了梳理和总结;对场地分类指标进行了分析和评述,并对有代表性的中国、美国、欧洲、日本、土耳其、智利、尼泊尔、伊朗、韩国、澳大利亚和新西兰等国家和地区抗震设计规范中的场地分类方案开展了对比研究。在此基础上,重点讨论了我国现行抗震设计规范中场地分类存在的问题,并提出了这一领域今后需要研究的若干关键问题。本文的工作对从事场地分类研究的科技人员有一定的参考价值。
The site conditions play an important role on ground motion indicated by observed data of strong earthquakes and seismic investigation.Currently it is well recognized around the world for classifying sites according to site conditions and stipulating design ground motion parameters for different sites regarding seismic design code from the perception of engineering seismology,as well as an important research content of earthquake geotechnical engineering.It is reviewed and summarized in the paper for the research process of site classification of the seismic code home and abroad.Meanwhile,analysis and comment are performed for the site classification indexes.In addition,it is launched to review and compare the site classification schemes of different countries by taking the representative ones as China,the United States,Europe,Japan,Turkey,Chile,Nepal,Iran,South Korea,Australia and New Zealand.The keynote is to focus on the problems of site classification in the current seismic design code of China based on this,and proposed several key issues that need to be studied on site classification in the future.The results of these analyses will bring some added value for the reference of researchers who are interested in site classification.
