摘　　要：建立了高薄拱坝坝身稳定分析的系列概化模型,采用通用有限元软件ANSYS的屈曲分析功能,计算其稳定超载系数并用突变理论分析了高薄拱坝的稳定问题,分析表明,其稳定性判别结果与有限元稳定计算结果相吻合.A series of generalized stability analysis models of high and thin arch dams were established, and the stability overload coefficients were calculated with the buckling analysis function of ANSYS based on FEM. The stability of darn body was also analyzed using catastrophe theory. The results coincide with the FEM results.

关 键 词：高薄拱坝 坝体屈曲 有限元 稳定超载系数 突变理论
