摘要
采用有限元软件对某水电站厂房坝段进行动力分析,建立厂房坝段的计算模型,利用solide45块体单元进行离散,分析厂房坝段的自振特性,并通过反应谱法计算结构的抗震动力响应。将动力计算结果与静力计算结果叠加,成果显示厂房坝段的变形和强度满足要求,为工程提供依据。
The software of FEM was used to analyze dynamic of a plant monolith of the some hydro project. With the software, calculation model of a plant monolith of a power station was established, this paper uses solide45 block elements to divide and analyzes its self-vibration characteristics, and the anti-seismic dynamic responses of structure was calculated through the spectrum. Finally, by the superposed results of dynamical and static calculation results, it showed that the deformation and strength of a plant monolith, all can meet the requirements, which provides the basis for the design of project.
