Finite Element Method for the Dam Deformation Analysis and Forecasting

在阐述有限元法基本理论的基础上,研究了采用ANSYS有限元分析软件进行大坝有限元建模、网格划分、荷载及边界条件施加等大坝变形分析的方法,在用有限元法获得水位位移分量及温度位移分量后建立大坝位移确定性模型,从而对大坝的变形监测提供可靠的依据。

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.
