| Abstract: | 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 dam body was also analyzed using catastrophe theory.The results coincide with the FEM results. |

| Keywords: | high and thin arch dam dam buckling FEM stability overload coefficient catastrophe theory |
