摘　　要：以核电站导流堤围堰稳定性问题展开研究,在进行导流堤围堰设计优化、比较的基础上,介绍了有限元数值模拟分析方法,以及有限元强度折减原理与方法;选用施工围堰最为不利断面进行稳定性分析验算,考虑渗流作用与流固耦合影响、强度折减(SSR)进行稳定性分析.分析结果表明,核电站导流堤围堰有限元强度折减稳定性分析能够验证工程实践,研究结果可为类似工程提供技术指导.The research on the stability of diversion dike and cofferdam of nuclear power station has been developed by introducing the finite element numerical simulation method and the finite elements strength reduction theory and method based on design optimization and comparison of cofferdam and diversion dike. The most disadvantage section is selected to do the stability analysis checking by considering seepage, fluid-solid coupling effect and strength reduction （SSR）,which can verify the actual engineering clearly, and the research results can provide technical guidance for similar projects.
