摘　　要：抗震设防烈度是建筑抗震设计的一项基本参数,许多国外工程建设项目由于所在国无可供执行或参照的抗震设计规范,使得项目前期的场地勘察与结构设计缺乏相应依据。文章介绍了全球地震模型开源平台发布的全球地震危险性图,通过分析其基准场地与国标场地类别的联系,探求全球地震危险性图地震动峰值加速度与抗震设防烈度的对应关系,为国内外工程建设项目的岩土工程勘察和抗震设计提供参考依据。Seismic precautionary intensity is a fundamental parameter for seismic design of buildings.For many foreign engineering construction projects there are no seismic design codes being executed or referenced in those countries,it results in a lack of corresponding basis for ground investigation and design of structures in the early stage of the projects.The Global Seismic Hazard Map released by the open-source platform of Global Earthquake Model is briefly introduced in this paper.By analyzing the relationship between its benchmark site and the site category in Chinese codes,the corresponding relationship is discussed that is between the peak ground acceleration which is obtained in the Global Seismic Hazard Map and seismic precautionary intensity.It provides reference basis for the geotechnical investigation and seismic design of foreign engineering construction projects.
