基于拱坝稳定的拱圈线型优化探讨

Optimum Discussion of Arch Ring Type Based on Arch Dam Stabilization

应用有限元法对拱坝的不同拱圈线型进行了屈曲分析,获得了基于拱坝稳定的合理拱圈线型,提出了拱坝稳定最优中心角的概念。

This paper carries out bucking analysis for the different arch ring types of the arch dam with the finite element method （FEM）, and obtains the rational arch ring type on the basis of arch dam buckling. And bucking optimum central angle is proposed in this article.
