Among the methods of arch dam stability and slope stability analysis
the finite element method (FEM) can take almost all factors into consideration; especially seepage,material constitutive relationship ,structure a deformation
stress distribution
complicated material distribution and boundary contact status etc. But there is no corresponding evaluation system provided by the design code. On the contrary
there are specific indices in the rigid body limit stability analysis. In this paper
the FEM results are re-analyzed with the limit stability analysis formula
to get the similar safety factors
which could be easily compared and estimated. Finally
the method has been successfully applied to Jingpin Arch Dam design.
