国内外不同抗震设计规范中场地分类方法的内在关系研究

目前国内外不同行业（如建筑、铁路、公路、构筑物、电力、水利等）在抗震设计的场地分类方面,主要考虑各自的应用特色和具体需求,尚无一套所有相关行业统一认可的标准和依据。本文归纳和对比了国内外多种行业规范在场地土和场地类别划分方面的依据和方法,并讨论和分析了各规范之间的主要异同和内在关系。在此基础上,指出我国在抗震设计方面,应制定一种兼顾多行业需求的通用型场地分类规范,以更好地适应各类工程建设的需求。

Study on the Relations of Site Classification Methods in Seismic Design Standards between China and Abroad

At present, different industries, such as architecture, railway, highway, construction, electric power and hydraulic engineering in China and abroad have their own site classification methods and standards in seismic design. Because each industry has its own specific considerations and requirements, the site classification methods and standards are somewhat different from each other, and there is no a set of universal methods or standards of site classification which are suitable for all industries. In this paper, we summarized similarities and differences of site classification methods and standards in seismic design of different industries in China and abroad, and discussed the relations among different site classification methods and standards. Finally, we concluded out that it is necessary for China to establish a set of universal site classification methods and standards in seismic design in order to meet the requirement of engineering constructions for different industries.
