Earthquake is one of the most destructive natural disasters. Since several destructive earthquakes have occurred in recent decades, seismic risk analysis for critical engineering structures has become one of the most important and popular topics in earthquake engineering. Nuclear energy industries world-wide are launching an unprecedented and extensive re-evaluation of seismic hazards and risk to nuclear power plant (NPP) systems. Furthermore, nuclear energy regulators and utilities are taking a critical look at the existing methods of estimating seismic risk of NPPs. A number of shortcomings have been recognized in the existing methods of seismic risk analysis.

地震是最具破坏性的自然灾害之一。由于近几十年来发生了多起破坏性地震，对重要工程结构进行地震风险分析已成为地震工程领域最重要和最热门的课题之一。世界范围内的核能工业正在对核电站（NPP）系统的地震危害和风险进行前所未有的广泛重新评估。此外，核能监管机构和公用事业公司正在对现有的核电站地震风险评估方法进行严格审查。在现有的地震危险性分析方法中，已经认识到一些缺点。
