摘　　要：有限元等效应力是拱坝设计规范规定的强度校核方法和设计标准,在介绍了其基本理论和计算方法的基础上,结合工程实例介绍有限元等效应力的运用,按规范规定的强度标准进行校核,计算结果合理有效,同时与其它计算方法进行了比较分析,揭示了拱坝等效应力计算研究对工程的意义,得出有益结论,为拱坝结构计算研究提供参考.The finite element equivalent stress is the method of checking the strength in the arch dam design specification and the design standard. Based on the introduction of the basic theory and the calculating method, we illustrated the application of the finite element equivalent stress in the practical projects, checked it with intensity standards in the design specification. The calculation result is rational and effective. A comparative analysis of other calculation methods reveals that the equivalent stress is an effective method in the calculation and research of arch dam project, which provides sound reference for the research of arch structure.
