摘要

当前以及今后相当长一段时期,核电都将是中国积极发展的能源形式之一,保障核电安全是确保核电工程建设顺利实施和安全运营的关键。然而,中国幅员广阔,地质条件差异大,海域自然条件复杂;同时,中国地震活动范围广、强度大、频度高,基于标准化设计的核电工程结构在建设过程中面临着诸多问题。尤其是2011年日本大地震导致的福岛核电事故的教训,对核电工程的抗震安全提出了新的问题。结合大连理工大学十几年来在解决我国核电工程结构抗震安全中的关键问题,以及在“地震作用下核电厂工程结构的功能失效机理及抗震安全评价”研究中所取得若干进展进行综述性介绍,主要包括核岛地基抗震适应性研究和核岛安全相关工程结构抗震防灾研究。

Abstract

uclear power is one of energy resources that China will vigorously develop for a long term from now on. The issue of nuclear power security guarantee is a key to ensure the smooth implementation and the safe operation of the nuclear power plant construction. However, because of the vast territory of China, the great differences in geological conditions and the complex natural conditions of ocean, as well as a wide range of seismic activity, high strength and high frequency of earthquakes in China, nuclear power buildings based on current standardized design methods are facing problems. Moreover, the lessons of the 2011 Fukushima nuclear accident due to destructive earthquake come out new problems to Chinese seismic safety of nuclear power engineering. In this paper, by combining engineering practice in recent years of nuclear power engineering seismic safety evaluation of the Dalian University of Technology, the key issues and the research methods in the structural seismic safety of Chinese nuclear power projects and some progress made by the Dalian University of Technology in the study of "the function failure mechanism and seismic safety evaluation of the nuclear power plant engineering structures under earthquake" are introduced. It mainly includes the method and strategy to analyze the foundational seismic adaptability of nuclear power plant, and seismic safety evaluation on water supply and drainage structures of nuclear power plant and seismic resistance and disaster prevention researches on engineering structures related to nuclear safety.
