摘　　要：拱坝的抗屈曲稳定性一直是未被重视的问题。按照拱梁分载法的思想,用弹性稳定理论分别对拱坝的拱圈和悬臂梁的抗屈曲稳定性进行了分析,得出拱坝的抗屈曲稳定性由坝顶拱圈控制的结论。分析了国内外部分已建拱坝的抗屈曲稳定性。<Abstrcat> The stability of arch dam against elastic buckling has always been ignored. Based on the arch-cantilever method, the stability of arch ring and cantilever beam against elastic buckling in arch dams are analyzed with the theory of elastic stability, and the conclusion is drawn that the stability of arch dam against elastic buckling is governed by the top arch ring. Stability of some completed arch dams both at home and abroad are also analyzed.
