摘　　要：研究拱脚水平方向弹性支承拱的屈曲,提供弹性支承拱在3种荷载下的线性分析结果,分析拱的对称屈曲和反对称屈曲,得到对称屈曲和反对称屈曲的分界。最后提出临界轴力的计算公式及设计建议。It was studied the bucklings of horizontally elastically supported arches, and the linear analytic results of the horizontally elastically-supported arches under three loads were also presented. The symmetrical and antisym- metrical bucklings of such arches were analyzed, and a demarcation between the symmetrical buckling and antisymmetrical one was got. The formula for calculating the critical axial force as well as the recommendations on design were put forward.
