| Abstract: | Based on expounding the theory of finite element method, the key to the study of this paper focus on the finite element method of dam deformation Analysis adopting ANSYS finite element software,include building a dam finite elemen model,net partition , exerting load and border condition,build the dam displacement determinacy model using finite element method after gaining water level displacement component and temperature displacement component, thereby provid credible basis to the dam deformation monitors. |
