重力坝三维有限元仿真分析

Analysis of Gravity Dam Three-dimensional Finite Element Simulation

采用三维有限元软件(ANSYS)对大坪菁水库主坝进行了受力分析。结果表明:坝体的应力符合有限元计算的一般规律,计算结果反映了重力坝的实际应力分布情况。运用有限元软件(ANSYS)进行重力坝应力计算可节约时间,提高工作效率,有较大的实用价值。

Using three-dimensional finite element software（ANSYS） to analyze the main dam of Dapingjing Reservoir. The result shows that the stress of the dam body accords with the general rules of FEM（finite element method）, the calculation result reflect the actual stress distribution of gravity dam. Using finite element program（ANSYS） to calculate stress of gravity dam can save time and improve work efficiency, it has a large practice value.
