基于ANSYS的混凝土重力坝抗震性能分析

Analysis of Seismic Performance of Concrete Gravity Dam Based on ANSYS

利用Ansys软件建立了重力坝结构的有限元分析模型,采用静力理论和动力理论,对坝体进行了静力分析和动力分析,得到了坝体变形图、合位移等值线图、有效应力等值线图、坝体振型图。通过分析可以得到地震载荷对坝体产生的影响,并为坝体的设计提供理论依据。

The finite element analytical model of the gravity dam is established by using Ansys software, to make a static analysis and a dynamic analysis of the dam with the static theory and the dynamic theory, obtaining the dam deformation graph, the displacement isogram, the effective stress isogram and the vibration mode graph of the dam body. The analysis shows the effect of earthquake load on the dam body, which provides a theoretical basis for design of the dam.
