重力坝抗震性能有限元分析

Finite-Element Analysis of Earthquake Resistant for Gravity Dam

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。

Finite-element analysis model of gravity dam is established.The dam body was analyzed by using static theories and dynamic theories,by simulation,distortion,displacement,effective stress and vibration types of the dam body are obtained.Finally,good results are obtained based on analysis and calculation of a gravity dam.
