日本福岛事故后核电厂抵御极端自然灾害能力受到广泛关注,世界上各个国家都积极开展相关研究,而地震一直是核电厂工程安全问题的主要威胁之一,因此核电厂的抗震安全性更是成为业界分析研究的重点.楼层反应谱作为核电厂系统、结构和部件抗震设计的输入,其计算分析是核电厂抗震分析的重要环节,其结果对于核电厂的抗震安全水平起着举足轻重的作用.本文以中国核电工程有限公司自主研发的三代机型ACP1000标准设计为例,通过介绍楼层反应谱的输入、分析过程和方法,来阐述合理确定符合国情的地震输入、采用先进的建模和分析方法,对完善核电厂的抗震设计、提高核电厂的抗震安全性具有重要意义.

@@@@ The competence of resisting nature extreme disaster is widely concerned after Fukushima nu-clear incident in Japan. Many countries carry through investigation actively. The seismic is one of primary threat-ens for nuclear power plant safety. Therefore the seismic ability of nuclear power plants becomes the investiga-tive emphasis. The floor response spectra is the input of the seismic design for nuclear plant systems,structures and components,and the important part of the seismic design,which is holding the balance in nuclear plant seis-mic safety. In this paper we use the third generation nuclear power plant example that is ACP1000 normal design excogitated by the China Nuclear Power Engineering Co.,LTD. themselves to expatiate the reasonable seismic input and the advanced analysis method for China. Through introducing the input,the analysis process and the method about the ACP1000 floor response spectra are calculated. Then it has significant effect for improving the nuclear power plant seismic design and seismic safety.
