有限元等效应力在拱坝应力设计中的应用

he finite element equivalent stress is one of two methods of checking the strength that arch dam design specification provided, but also is the design standards of the arch dam intensity, and introduce the development, the basic theory and the calculate measure of it, combine with the project presente the finite element equivalent stress in the arch dam design, accordance with the provisions of intensity standards to check it, the results is rational and effective, and it reveals the effect of arch dam equivalent stress in use of the calculation and research of project, it obtains useful conclusions and provides reference for the research of arch structure.
